Best ResponseYou've already chosen the best response.0the power of 3 is the outside function, or f(x) and 2x7 is the inside function or g(x)

Best ResponseYou've already chosen the best response.2So f(x)=x^3 and g(x)=2x7 correct :)

Best ResponseYou've already chosen the best response.2f is the outside function g is the inside 2x7 is inside the ( )^3

Best ResponseYou've already chosen the best response.2so g is 2x7 f is x^3

Best ResponseYou've already chosen the best response.2\[f(g(x))=f(2x7)=(2x7)^3 \text{ since } f(x)=x^3 \text{ and } g(x)=2x7\]

Best ResponseYou've already chosen the best response.0ok so you would set it up x^3(2x7)^2?

Best ResponseYou've already chosen the best response.2If g(x)=2x7, then g'(x)= If f(x)=x^3, then f'(x)=?

Best ResponseYou've already chosen the best response.2\[(f(g(x))'=f'(g(x))\cdot g'(x)=f'(2x7) \cdot 2\]

Best ResponseYou've already chosen the best response.2Now to find f'(2x7) you need to plug 2x7 into f'

Best ResponseYou've already chosen the best response.2f'(x)=3x^2 f'(2x7)= <to find this one replace x with 2x7
