Question

Given the relation y = -4x^2 - 8, if the input is 2, what is the output?

A. 8

B. -8

C. -16

D. -24

Answer 1

The output for the quadratic equation y = -4x^2 - 8 when the input is 2 is -24, corresponding to option D.

Step-by-step explanation:

When given the quadratic equation y = -4x^2 - 8 and an input of 2, we can find the output by substituting the input value into the equation. We calculate as follows:

• y = -4(2)^2 - 8
• y = -4(4) - 8
• y = -16 - 8
• y = -24

Therefore, the output when the input is 2 is -24, which corresponds to option D.
