Question

f(x)=8
(3)^
x−2
+2
. 
The graph of
f(x)
is stretched vertically by a factor of 3 to form the graph of
g(x)
. 
What is the equation of 
g(x)
?
 

g(x)
= 

Answer 1

You have some funky formatting there. I read it as

f(x) = 8*3^(x-2)+2

but it doesn't really matter what f(x) is. Stretching by a factor 3 just means that

g(x) = 3*f(x)
