Question

Let f(x) = x + 8 and g(x) = x2 - 6x - 7. Find f(g(2)).

Answer 1

Answer choice
-5

4

-2

7

Answer 2

\[\Large\rm f(\color{orangered}{x})=(\color{orangered}{x})+8\]\[\Large\rm g(\color{orangered}{x})=(\color{orangered}{x})^2-6(\color{orangered}{x})-7\]Let's start by evaluating our function g(x) at x=2,

Answer 3

\[\Large\rm g(\color{orangered}{2})=(\color{orangered}{2})^2-6(\color{orangered}{2})-7\]

Answer 4

What do you get for g(2)?

Answer 5

first find g(2) as shown above by @zepdrix
then use this value as x to find f(x)
