Question

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

Answer 1

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.
