Given the functions f(x) = 6x + 11 and g(x) = x + 6, which of the following functions represents f[g(x)] correctly? f[g(x)] = 6x + 47 f[g(x)] = 6x + 17 f[g(x)] = 6x2 + 47 f[g(x)] = 6x2 + 17

    f(g(x)) means that you have to put g(x) as the value of x in f(x)

    just replace x with x + 6 so f(x +6) = 5(x + 6) + 11 then just simplify

    oops should be f(x + 6) = 6(x + 6) + 11 sorry for the typo

    so u'll have - f(g(x)) = 6(g(x))+11 f(g(x))=6(x+6)+11 f(g(x))=6x+36+11 f(g(x))=6x+47

    just find the value of g(6) = 6 - 8 then substitute the answer into f(x)

    okay so g(6) = -2 then I divide?

    then you substitute f(-2) = 6(-2) + 12
