Question

Evaluate the indicated function for f(x) = x2 + 2 and g(x) = x − 7. (f/g)(8)

Answer 1

Plug in 8 in the place of X in both equations.
f(x) = 2(8) + 2
f(x) = 16 + 2
f(x) = 18

g(x) = -7(8)
g(x) = -56

Then put f(x) over g(x). You should now have ...

`(18)/(-56)`
Simplify this fraction by dividing the top and bottom by 2
Your final answer is

`-(9)/(28)`
