Best ResponseYou've already chosen the best response.1Hint: If f(x) = 2x + 1 And r(x) = 3x  2 f o r(x) = f(r(x)) = 2x + 1 = 2(r(x)) + 1 = 2(3x2) + 1 = 6x  4 + 1 = 6x  3 We are creating new functions by substituting old ones into other old ones.

Best ResponseYou've already chosen the best response.1Just did. Your turn. If \(g(x) = \dfrac{x4}{x+3}\), what is \(g(5)\)?

Best ResponseYou've already chosen the best response.1would that answer to the question be 2x−5/2(x+1)

Best ResponseYou've already chosen the best response.1You didn't answer my question. What is \(g(5)\)?

Best ResponseYou've already chosen the best response.1is it the same as saying g(h(x))? just wanted to know before i asnwer

Best ResponseYou've already chosen the best response.1That's the next question. First, I want to see if you understand the concept of substitution into a function definition. You can answer wither question. \(g(h(x))\;or\;g(5)\).

Best ResponseYou've already chosen the best response.1\(g(5) = \dfrac{54}{5+3}\) \(g(h(x)) = \dfrac{h(x)4}{h(x)+3}\) That's ALL I'm looking for. Now, substitute in that last statement the definition for h(x) and do some simplifying.
