    f (-2) = 5

    Step-by-step explanation:

    we are given with a function f (x) = - 4x - 3

    we are asked to determine

    f (-2)

    in order to find f (-2) we will substitute x = - 2 in our function f (x)

    f (x) = -4x-3

    f (-2) = - 4 (-2) - 3

    =8-3

    =5

    Hence f (-2) = 5
