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.

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

a. 3 ≤ x ≤ 12
b. 3 ≤ x ≤ 7
c. 2 ≤ x ≤ 12
d. 2 ≤ x ≤ 7

The correct answer is b. The domain of the function is in terms of x, so we are looking at the x-axis. The line stretches from 3 to 7 on the x-axis, so we know that b is our answer.

The domain is the X values which are given on the horizontl axis, which is the quantity of blue paint along the bottom of the graph.

The line starts at 3 and goes to 7.

The answer would be:

B. 3 ≤ x ≤ 7
