Explanation and solution s. Understand that a function from one set called the domain to another set called the range assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f x denotes the output of f corresponding to the input x.
The evidence statement references Math Practice 2 in the Common Core: Mathematically proficient students make sense of quantities and their relationships in problem situations. They bring two complementary abilities to bear on problems involving quantitative relationships: the ability to decontextualize—to abstract a given situation and represent it symbolically and manipulate the representing symbols as if they have a life of their own, without necessarily attending to their referents—and the ability to contextualize, to pause as needed during the manipulation process in order to probe into the referents for the symbols involved.
Quantitative reasoning entails habits of creating a coherent representation of the problem at hand; considering the units involved; attending to the meaning of quantities, not just how to compute them; and knowing and flexibly using different properties of operations and objects. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
Sketch a graph that exhibits the qualitative features of a function that has been described verbally. Although the question begins to tap into HSF. The first option, a set of ordered pairs, is incorrect. Two of the ordered pairs have an x value of 3 but have different y values.
As stated above, each element of the domain in a linear function must map to exactly one element of the range.
If the same x value gives two different y values, the set of ordered pairs does not represent a linear function or any type of function. The graph is correct. The table is incorrect. As with the set of ordered pairs, the same x value yields more than one y value. The description of how to find the perimeter of a square is correct. The word problem translates to an equation, which can be plotted as a non-vertical line and therefore represents a linear function, since it meets all the requirements for a function—each valid input has exactly one output—and for being linear.
The absolute value function is incorrect. Purple Mathdeveloped by Elizabeth Stapel, a math teacher from the St Louis area, has a series of four webpages that deal with linear functions and how they are represented, here.
She describes how they can be represented in tables, graphs, equations, and word problems, as shown here.K - 10th grade. Played times. Print Share Edit Delete. Live Game Live. Finish Editing. This quiz is incomplete! To play this quiz, please finish editing it. Delete Quiz.

Algebra 1 PARCC question: linear functions
Consider a quadratic equation with integer coefficients and two distinct zeros. If one zero is irrational, which statement is true about the other zero? The other zero must be rational. The other zero must be irrational. The other zero can be either rational or irrational. The four indicated points all have integer coordinates.

Using questions provided from PARCC practice exams, this graphic organizer shows students different types of questions on an Algebra 1 PARCC test, as well as the different types of questions they will see. Graphic Organizers.A local salsa company makes two types of salsa, tomato and corn.
Each batch of tomato salsa takes 2 hours to prepare and 4 hours to package. Each batch of corn salsa takes 2. There are 4 preparation workers and 7 packaging workers in the company. Each of them works 40 hours per week.
Create a system of two inequalities that relates the number of batches of tomato salsa, tand the number of batches of corn salsa, cthat can be made by the 4 preparation workers and the 7 packaging workers each week.
You must select two inequalities. Which combinations of batches of salsa could be made in one week based on the constraints?
In order to maximize productivity, how many batches of salsa should be made if the company owner wants 20 batches of corn salsa?
The company owner decides to only make corn salsa one week prior to a local festival. Given the same constraints, what is the maximum number of batches of corn salsa that can be made in one week? Answer and references.
Specifically, Standard HSA. For example, represent inequalities describing nutritional and cost constraints on combinations of different foods. Example of a solution strategy there are others.
For Part A, if the company is producing both corn and bean salsa, we first consider just the production of the workers who make salsa: 2 hours for tomato, and 2. There are 4 workers making salsa the other 7 package the salsa.
If we consider these inequalities as a system of two inequalities in two unknowns, we can solve it. Use a graph to plot the inequalities and check the boundaries. In the graph below, I plotted the two inequalities:. For the graph, the number of corn salsa batches is plotted along the x axis, and the number of tomato salsa batches along the y axis.
Since each batch of tomato salsa takes two hours to make, the graph should go through the point 0, 80which makes it the blue line. The graph for the packagers, then, goes through the point 0, The half-plane in the region below each line is shaded, because the line represents the maximum amount of tomato and corn salsa that can be made or packaged.A: In order to solve for A, both sides of the equation may first be multiplied by 3.
A: Three equations may initially be written to represent the given information. Now, the expressions for l and j may be substituted into the equation, representing the sum of their ages. Thus, Sue is 8 years old. Rounding to the nearest cent gives 17 cents. C: From A. From P. D: If she removes 13 jellybeans from her pocket, she will have 3 jellybeans left, with each color represented. If she removes only 12 jellybeans, green or blue may not be represented.
A: 50 cents is half of one dollar, thus the ratio is written as half oforto x. C: The given equation should be solved for x. A: You will need 40 packs of pens and 3 sets of staplers. Thus, the total cost may be represented by the expression, 40 2. C: Substituting 3 for y gives 33which equals 27 27 - 3or 27 Thus, the expression equals Close Search.
