Let f(x)=12x2+4.

the function g(x) is a vertical stretch of f(x) by a factor of 4.

what is the equation of g(x)?

enter your answer in the box.
g(x) =

Step-by-step explanation:

given f(x)=

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

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
