Question

5. (03.01) 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: Line graph Color Mix, Quantity of Blue Paint, in mm, the X axis and Quantity of Green Paint, in mm, the Y axis. X axis has a scale from 0 to 10 increments of 1. Y axis has a scale of 0 to 20 increments of 2. Straight line 1, 2 and 9, 14 is drawn Which statement best describes the domain of the function represented in the graph? (1 point) 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

Answer 1

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

Explanation:

The straight line passes through the points (1, 2) and (9, 14)

The domain represents the x-values of the graph.

Here the x-values from 1 to 9 inclusive.

Therefore, the domain = [1, 9]

Answer: 1 ≤ x ≤ 9 or x is between 1 and 9, inclusive.

Thank you.
