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

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

0 ≤ x ≤ 9 or x is between 0 and 9, inclusive

2 ≤ x ≤ 14 or x is between 2 and 14, inclusive

1 ≤ x ≤ 9 or x is between 1 and 9, inclusive

1 ≤ x ≤ 14 or x is between 1 and 14, inclusive

anonymous · Answer

On the graph, the x-values are on the bottom. The line starts at x=1, and ends at x=9. X has to be between these 2 choices, because the line doesn't go any futher. The answer would have to be C because x would have to be greater than or equal to 1, and less than or equal to 9.
