Answer:
D
Step-by-step explanation:
(f • g)(x)
= f(x) × g(x)
= (x + 4)(3x² - 7)
each term in the second factor is multiplied by each term in the first factor , that is
x(3x² - 7) + 4(3x² - 7) ← distribute both parenthesis
= 3x³ - 7x + 12x² - 28
= 3x³ + 12x² - 7x - 28 ← in standard form
Nineteen million, two hundred sixty-six thousand, four hundred twenty! :)
The answer would defintley be 69 if you want the right answer.
28.
2 to the third power is 8. Therefore, the answer is 28.
Hope this helps!
