Okay, so all this question wants you to do is plug in 2 for x and solve for your output, aka y.
y = -4x² - 8
when x = 2....
y = -4(2)² - 8
y = -16 - 8
y = -24
so, when your input is 2, your output is -24.

Answer:
x² + 4x + 3
Step-by-step explanation:
to find f(g(x)), substitute x = g(x) into f(x)
f(g(x)) = f(x + 2) = (x + 2)² - 1 = x² + 4x + 4 - 1 = x² + 4x + 3
