Answer:
2x³ + 5x² - 12x
Step-by-step explanation:
The correct answer doesn't seem to be listed...
(fg)(x) = (2x² - 3x)(x + 4)
Which equals...
2x²(x) + 2x²(4) + (-3x)(x) + (-3x)(4)
Which simplifies to...
2x³ + 8x² - 3x² - 12x
2x³ + 5x² - 12x
Answer: 17
Steps:
1. Plug in (3) into “x” of the g(x) equation:
g(3) = (3)^2 + 4
g(3) = 9 +4
g(3) = 13
2. Plug in g(3) value into “x” of the f(x) equation:
f(g(3)) = x + 4
f(g(3)) = 13 + 4
f(g(3)) = 17
