    f ( - 2) = - 7

    Step-by-step explanation:

    To evaluate f ( - 2) substitute x = - 2 into f (x), that is

    f ( - 2) = 5 ( - 2) + 3 = - 10 + 3 = - 7

    In this question, you're solving the equation by plugging - 2 into x.

    Plug - 2 into x:

    f (x) = 5 (-2) + 3

    Solve:

    f (x) = 5 (-2) + 3

    f (x) = - 10 + 3

    f (x) = - 7

    Answer:

    f (x) = - 7
