Best ResponseYou've already chosen the best response.1For your first question, they've already given you the value of f(x) and g(x) so all you want to do is plug it into the equation. :) \[f(x) = 9x + 4 \] \[ g(x) = 5x + 1\] Therefore g(x)  f(x) would equal: \[5x + 1  ( 9x + 4) = ? \]

Best ResponseYou've already chosen the best response.1For the next question: f (x) = 9x  5 f (2) = 9(2)  5 = ? Then after you find out what f(2) equals to, we want to find what g(4) equals to. So, g (x) = 6x g (4) = 6(4) = ? Then f(2)  g(4) = ?

Best ResponseYou've already chosen the best response.1not quiteeee. So what did you get for f(2) = ?

Best ResponseYou've already chosen the best response.1Note: f(2) = 9(2)  5 = 18  5 = 13 g(4) = 6(4) = 24 f(2)  g(4) = 13  24 = ?

Best ResponseYou've already chosen the best response.1For question 3. You need to multiply both f(x) and g(x) together. Since \[f(x) = x^2 + 6x\] and \[g(x) = 2x^3\] Multiply both together and we get: \[f(x) \times g(x) = 2x^3 (x^2 + 6x) = ?\]

Best ResponseYou've already chosen the best response.1now for the final one. Just multiply both and see which one is correct. So what do you get when you multiply f(x) and g(x) together? \[f(x) \times g(x) = 5x ( 3x  2) = ?\]

Best ResponseYou've already chosen the best response.1A is correct. C is correct. But what about D?? Note: when you multiply anything by 0, the answer will be 0
