Given the functions f(x) = 7x + 13 and g(x) = x + 2, which of the following functions represents f[g(x)] correctly?
f[g(x)] = 7x + 15
f[g(x)] = 7x + 27
f[g(x)] = 7x2 + 15
f[g(x)] = 7x2 + 27

Best ResponseYou've already chosen the best response.0g(x)=x+2 so you plug in (x+2) for x in f(x)...what would that look like before you distribute it out and combine like terms?

Best ResponseYou've already chosen the best response.0that's f(x)...take a step back...what would you do if it told you to evaluate f(x) for x=3?

Best ResponseYou've already chosen the best response.0perfect! you'd plug it in! but here's the thing...you don't have a value for x. you have (x+2), but it still works the same way. You plug it in to f(x) so you get 7(x+2)+13
