Answer: Answer: If f(x) = x + 2, g(x) = x – 4, then (f g)(x) = x2 - 2x - 8.
Let's solve this step by step.
Step-by-step explanation:
Step-by-step explanation:
Given functions f(x) = x + 2, g(x) = x – 4.
(f g)(x) = f(x) × g(x)
(f g)(x) = (x + 2) × (x - 4)
(f g)(x) = x2 + 2x - 4x - 8
(f g)(x) = x2 - 2x - 8
Hence, if f(x) = x + 2, g(x) = x – 4, then (f g)(x) = x2 - 2x - 8.
