Question

Which equation represents exponential growth and has a vertical stretch of 2?
A. y = 2(3x)
B. y = 3(.11)x
C. y = 2(1/2)x
D. y = x(1/6)2

Answer 1

I do not want to tell you the answer,but I can try to explain it:
y = a(1 + b)^x
B= growth factor
if b is > than 1 it is growth
if b is less than 1 it is decay
a= vertical stretch

Which one do you think is correct

Answer 2

I think you have the equation written wrong?
