Homework Help: Pre-Calculus

Posted by Shreya on Thursday, September 27, 2012 at 9:48pm.

Composition of Functions

f o g(x)=f(g(x)) --> I know that this is eqivalent to f(g(x))

Given f(x) = 2x+1, and g(X) = 3x+1 find:f o g(x)=f(g(x))

This is what I did, but I don't think Ive solved it correctly

f(g(x)) = f(x-3)
f(x-3) = 1(x-3)-3x+2
=x-3-3x+2
f(g(x)) = -2x-1

The perimeter P of a square and the area A of a square r functions of its side length S. write area as function of Perimeter. ?

Also write out the square's area as function of length of its diagonal.
