Let f(x)=(x+2)2.

Let g(x)=3(x+2)2.

Which statement describes the graph of g(x) with respect to the graph of f(x)?

It is translated right 3 units.

It is stretched vertically by a factor of 3.

It is compressed horizontally by a factor of 3.

It is translated up 3 units.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
