Answer:

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.
