Question

Keira created color panels for a wall using a mix of only red and blue paints. She plotted the quantities of red and blue paints used for each mix and connected them using a line segment as shown in the graph below.

A line graph titled Color Mix, with Quantity of Blue Paint (in millimeters) on the X axis and Quantity of Red Paint (in millimeters) on the Y axis. The X axis has a scale from 0 to 9 with an increment of 1. The Y axis has a scale of 0 to 18 in increments of 2. A straight line connecting (3, 2) and (7, 12) is drawn.

Which statement best describes the domain of the function re

Answer 1

Did you figure it out on your own? You didn't write the statements to choose from.

Answer 2

whoops one sec

Answer 3

Which statement best describes the domain of the function represented in the graph?

3 ≤ x ≤ 12 or x is between 3 and 12, inclusive

3 ≤ x ≤ 7 or x is between 3 and 7, inclusive

2 ≤ x ≤ 12 or x is between 2 and 12, inclusive

2 ≤ x ≤ 7 or x is between 2 and 7, inclusive

Answer 4

Remember, domain is all the values x can have.

Answer 5

c?

Answer 6

The point on the lower left has an x-value of 3, and the point on the upper right has an x-value of 7. Those two values, 3 and 7, anre part of the domain. The fact that there is a line drawn from one point to the other shows that all points between 3 and 7 are also part of the domain.

Answer 7

im confused

Answer 8

x can be 3, 3.1, 3.2, 3.3, ... 4.125, ... 5, 5.1, ... 6, 6.01, 6.5, 6.7, ...6.9, 7
All values from 3 to 7. Which choice above means all numbers from 3 to 7 including 3 and 7?

Answer 9

Look in the graph. All values of x from 3 to 7 have a point in the line above. The domain is from 3 to 7 including 3 and 7. To the left of x=3 there are no points, and to the right of x=7 there are no points.
