F (x) = x2-5, g (x) = 15-x, find (f+g) (-6)

Hello!

To solve for (f + g) (-6), we substitute the value - 6 into each function and add the answers together.

f (-6) = (-6) ² - 5

f (-6) = 36 - 5 = 31

and

g (-6) = 15 - (-6)

g (-6) = 21

(f + g) (-6) = 31 + 21 = 52

Therefore, the final value of the function (f + g) (-6) is equal to 52.
