    What Conditions Make a∘b Equal to b∘a for Given Functions?

    Homework Statement Let a=fx+g and b=hx+i. For which real numbers f,g,h,i a∘ b = b∘ a Homework Equations The Attempt at a Solution a∘ b(x)=(a(b(x))= h(fx+g)+i= fhx+gh+i b∘ a(x)=(b(a(x))= f(hx+i)+g= fhx+fi+g I'm kind of stuck here as I don't think I know what the question is...
