Hi, I've been doing Pre-Calculus by Correspondence for a little while now, and after a while everything was going fine, but now I'm having trouble with the following composite Function question:
F(x) = (3x)/(x^2 + 3x + 2), g(x) =(5x)/(x+1)
simplified expression for (f•g)(x), I get about as far as f((5x)/(x+1))
so I write out: (3(5x)/(x+1))/( (5x)/(x+1)^2 + 3(5x)/(x+1)+2)
And then it confuses me, I’ve looked through my book and I can’t find an equation nearly as difficult as this. How would I go about solving this?
