Question

If f(x) = x² - x -6 , then f(1) +f (3) =

Answer 1

f(x) = x² - x -6

therefore:

f(1) = 1² - 1 -6 = 1 -1 -6 = -6

f(3) = 3² - 3 -6 = 9 -3 -6 = 6-6 = 0

So: f(1)+f(3) = -6+0 = -6

Hope this solves your doubt

Answer 2

Step-by-step explanation:

f(1)=1^-1-6

=1-1-6

=1-7

=-6

f(3)=3^-3-6

=9-3-6

=9-9

=0
