Question

(x)=x^2+6 and G(x)=x+8\x find (g o f) (-7) help pleaaaaase :)

Answer 1

what is f(-7)?

Answer 2

find (g o f) (-7)

Answer 3

in order to find that, we first must find f(-7); what is f(-7)?

Answer 4

(-7)^2+6 ? and (-7)+8 / (-7)???

Answer 5

(-7)^2 + 6 is all we need at first; since that is f(x)

g(x) depends on the value of f(x) in this case so;

would you agree that f(-7) = 55?

Answer 6

(g o f)(x) means: g(f(x))

(g o f)(-7) means: g(f(-7))

IF f(-7) = 55; then we want: g(55)
