Question

I need to know the answer for he last one I got the first one correct.

Answer 1

Range is the set of all possibel y - values for the function.

d(x) = 30x

d(16) = 30(16)

d(16)= 480

So, the range is:

0 ≤ d(x) ≤ 480

To find the graph, replace x by 20

d(20)= 30 (20) = 600

So, for x=20 , y=600

The graph is:
