Hello.
The question is,
For exercise 37, find functions f and u so that [math]F(x)=f(u(x))[/math].
37.
[math]F(x)=(x^3+2x^2-8)^4[/math]
I have a couple questions:
1) Is the capital F important? My guess is yes, but if you could elaborate a little it would be appreciated.
2) Can you show me the steps to obtaining the answer. My book gives the answers for f and u, but I cannot figure out the steps to getting the answer. In particular, it says that [math]f(u)=u^4[/math]. I have no idea why this is.
Thanks in advance
