Find the Composition of Quadratic Function and Linear Function EX1

Find the composition, (f∘g)(x), of a quadratic function, f(x)=x^2+2x-4, and the linear function, g(x)=3x+2. The composition is found using (f∘g)(x)=f(g(x))=f(3x+2). This requires the squaring of a binomial that is carried out using FOIL.
