i have 2x^2-2 for the answer

OpenStudy (mertsj):

This is the same thing. Did you try it?

OpenStudy (anonymous):

no i need to be stepped through it.....

OpenStudy (mertsj):

Replace every x in the function g with the function x

OpenStudy (anonymous):

so.. is this how i would do it 2(x-5)^2+3

OpenStudy (mertsj):

The function g is x-5 Do you see the x?

OpenStudy (anonymous):

yeah i think so.... :/

OpenStudy (mertsj):

Replace that x with 2x^2+3

OpenStudy (anonymous):

g(x) = x-5. this x replace it?

OpenStudy (mertsj):

yes. g(f(x)) means replace each x in the function g with the function f

OpenStudy (anonymous):

so... would it be 2x^2+3x-5?

OpenStudy (anonymous):

@Mertsj

OpenStudy (mertsj):

I thought the function f was 2x^2+3 not 2x^2+3x

OpenStudy (anonymous):

yah ur right i was wrong
