Question

F(x) = 2x + 6, and g(x) = x2 + 6, find (g ○ f)(1)

Answer 1

The correct answer is 
g(f(1))
Plug 1 into the f function. 
f(1) = 2(1) + 6
f(1) = 8
Now evaluate g(8)
g(8) = 8^2 + 6
g(8) = 70

Hope this helps!

So in short your answer is 70

Answer 2

Putting the values we get the answer as 70
