F (x) = x²-3x-2 then f (-1) is given by

f (-1) = 2

Step-by-step explanation:

To evaluate this function at x = - 1, replace "x" in the equation with (-1) (you should use the parentheses as indicated here).

f (x) = x²-3x-2 becomes

f (-1) = (-1) ² - 3 (-1) - 2, or

f (-1) = 1 + 3 - 2, or

f (-1) = 2
