    The answer to your question is letter B

    Step-by-step explanation:

    Process

    1. - Write the function

    f (x) = - 2x² + 2x - 3

    Find f (5)

    2. - Substitute x for 5

    f (5) = - 2 (5) ⁵ + 2 (5) - 3

    3. - Simplify

    f (5) = - 2 (25) + 10 - 3

    f (5) = - 50 + 7

    f (5) = - 43
