f(x)+-2x+7, g(x)=x^2; what is g(f(x)) I got (-2x+7)^2=4x+49

Re: Is this right?

I'm assuming that by "+" in front of f(x) you meant "=".

If so, then g(f(x)) does in fact equal (-2x+7)^2. However, your final answer (when multiplied out) is wrong.

(-2x+7)^2=(-2x+7)(-2x+7)=4x^2-14x-14x+49=4x^2-28x+49
