Question

Let f(x)=12x2+4.

Answer 1

Answer:

$g(x)= 48x^2+16$

Step-by-step explanation:

given f(x)= $12x^2 +4$

The function g(x) is a vertical expansion of f(x) by a factor of 4.

when f(x) is vertically expansion  by 'a' f(x)  becomes a f(x)

For vertical expansion by a factor of 4  we multiply f(x) by 4

So $g(x)= 4(f(x))$

$g(x)= 4(12x^2+4)$

$g(x)= 48x^2+16$

Answer 2

G(X)=
16x^2+4
Parent function is y=x^2
