Question

im checking my answer I believe it is D

What is the effect on the graph of the function f(x) = x2 when f(x) is changed to 3f(x − 2)?
A) stretched horizontally and shifted up
B) stretched vertically and shifted right
C) compressed vertically and shifted left
D) compressed horizontally and shifted down

Answer 1

3(f - 2) = 3x^2 - 6;

So new f(x) = 3x^2 - 6;

When x = 0, f(x) = -6, so it shifts down

If it shifts down, all other options are excluded and D is the correct answer
