Final answer:
To find the value of (f g)(-2), substitute the given values into the composition function f(g(-2)). Without the value of f(-8), the exact value of (f g)(-2) cannot be determined.
Step-by-step explanation:
To find the value of (f g)(-2), we need to evaluate the composition function f(g(-2)). Since f(-2) = 4 and g(-2) = -8, we substitute these values into the composition function.
f(g(-2)) = f(-8)
The value of f(-8) is not given, so we cannot determine the exact value of (f g)(-2) without more information.
