If f(x) = x + 5 and h(x) = 3x then what is (f + h)(4)?
(f + h)(4) = 21


Answer explained:
(f + h)(x) = f(x)+h(x) = x + 5 + 3x = 4x + 5
(f + h)(4) = 4(4) + 5 = 16 + 5 = 21

f(x) = 3x + 5, g(x) = 4x - 9, h(x) = x + 6
What is f(g(0))?
f(g(0)) = -45

Answer explained:
f(g(x)) = f(x) * g(x) = (3x + 5)(4x - 9)
f(g(0)) = f(0) * g(0) = (3(0) + 5)(4(0) - 9) = 5 * -9 = -45
