Brody Dean · Answer 1

The function range is {-2, - 3, - 4}.

Step-by-step explanation:

I am assuming that the domain is 5, 10 and 15.

Thus the range will be the values of y when x is 5, 10 and 15.

When x = 5, y = 0.2 (5) - 5 = 1 - 5 = - 4.

The other values in the range are 0.2 (10) - 5 = - 3 and 0.2 (15) - 5 = - 2.
