It's all there (excepting the last right parenthesis).  What's stopping you from calculating it?

anonymous · Answer

can you help me on that because every answer that I come up with is wrong I am not getting it for some reason

tkhunny · Answer

Is there a problem statement to go along with it?

anonymous · Answer

I missed it so now I am on a new one (gof) (-4)

28(-4)^2-6(-4)+1

tkhunny · Answer

We're not getting anywhere.  You need to provide a complete problem statement.  What is g(x)?  What is f(x)?

anonymous · Answer

oh sorry

f(x)=2x
g(x)= 7x^2-3x+1

I have done all of the steps but the d which it says to find (gof)(-4) and evaluate and I can not figure out if you do -4*-4then times it to 28 or what so Im stuck

tkhunny · Answer

Can you write out g(f(x))?
