Question

Find (f•g) (-1) Let f(x) =-2x-1 and g(x) =x^2 -1

Answer 1

Answer:-1

Step-by-step explanation:

let g(x) foil into f(x)   =>    (-2(x^2-1)-1)

                                      = -2x^2+1

then put (-1) into the formula => -2(1)+1

                                                 = -1

that is the answer^^
