Best ResponseYou've already chosen the best response.0Well, function composition is mainly an exercise in writing things out properly, then simplifying. If I said simplify x + 2 + x + 5 it is pretty obvious it is 2x + 7. But if I say f(x)= x + 2 and g(x) = x + 5 then ask "What is (f + g)(x)?" it is less obvious, but it is the same thing. It just means you write out some more steps: (f + g)(x) = f(x) + g(x) (f + g)(x) = (x + 2) + (x + 5) (f + g)(x) = x + 2 + x + 5 (f + g)(x) = 2x + 7 That shows the steps, basically. Do similar things with your functions.

Best ResponseYou've already chosen the best response.0b is multiply. c is function inside a function. So you replace x in the outter function with the entore inner. So to take my example, f[g(x)] means I do this: x+2 (x+5)+2 x+7 I am putting the x+5 inside the x+2 in place of the x. So again, just use your functions and do the same thing.
