Step-by-step explanation:

Step 1: Define

y = -4x² - 8

x = 2

Step 2: Solve

  1. Substitute:                   y = -4(2)² - 8
  2. Evaluate:                      y = -4(4) - 8
  3. Multiply:                       y = -16 - 8
  4. Subtract:                      y = -24

Answer:

Given, input (x) is 2,

[tex]y = -4x^2 - 8\\y = -4(2)^2 - 8\\y = -4(4) - 8\\y = -16 - 8\\y = -24[/tex]

Output (y) is 24
