Question

Let F(x)=X^2-19 and G(x)=20-X.

Find (F/G)(6).


(F/G)(6)=_____
Make the answer an integer or fraction and simplify if needed.

Answer 1

Answer: 17/14

Explanation:

Given F(x) = x² - 19, G(x) = 20 - x

Then;

(F/G)(x) = F(x) / G(x) = (x² - 19) / (20 - x)

=> (F/G)(x) = (x² - 19) / (20 - x)

at x = 6, it means anywhere we see x in the function above, we should substitute 6. Therefore,

(F/G)(6) = (6² - 19) / (20 - 6) = (36 - 19) / (14) = 17/14
