f(x) — x2 and g(x) is 5x2, then g(x) is f(x) with a

A) none of these

B) different vertex

C) vertical stretch

D) vertical compression

if you mean f(x) = x^2

and g(x) = 5 x^2
f(0) = 0 and g(0) = 0
f(1) = 1 and g(1) = 5
f(2) = 4 and g(2) = 20
f(3) = 9 and g(3) = 45
etc ... upward faster on the right
