Question

What is the range of the function shown on the graph above?

A: -6 < y < 9
B: -6 C: 0 D: 0 < y < 7

Answer 1

D: 0 < y < 7

Explanation:

The domain is the input (i.e. the x values)

The range is the output (i.e. the y values)

So for the range, look at the y-coordinates of the end points of the line: (-6, 0) and (9, 7) ⇒ 0 < y < 7
