If f(x) = - 2x2 + 2x - 3, what is f(5)? A) -93 B) -43 C) -28 D) - 43/5

andrew-mc [135]

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
