Write the equation of the function g(x) if g(x) = f(x – 2) +4 and f(x) = x^3 + 2.
I already took the test that had this question, I just want to know how to solve it, please. I feel like it may be such an easy question, but I'm just overthinking it.

Best ResponseYou've already chosen the best response.2\[\huge\rm g(x)= \color{ReD}{f(x2)}+4\] so then you can substitutef(x2) with the result

Best ResponseYou've already chosen the best response.0OOHHH okay I got you, that makes so much more sense. I was completely thinking about it in a different way. I know how to do it now. Sorry about that. Thanks:) @Nnesha
