I would say no but i don't know how to do your problem by how your describing it sorry :(
Domain is inputs, input the domain for x
y=5(-1.2)-2
y=-6-2
y=-8
y=5(0)-2
y=0-2
y=-2
y=5(4)-2
y=20-2
y=18
range is {-8, -2, 18}
Answer: y = 52
Explanation:
13/3=4 1/3
4 1/3 times 12 = 52
Ratio explanation
(Times 4 1/3) 12:3 (divided by 4 1/3
New Ratio- 52:13
I believe it is an exponential function.
