D) -
43/5

Answer 1

Answer:

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
