The domain for f(x) and g(x) is the set of all real numbers. let f(x) = 3x + 5 and g(x) = x2. * find f(x) • g(x).* a) 3x^2 + 5 b) 3x^3 + 3x^2 + 5 c) x^2 − 3x − 5 d) 3x^3 + 5x2

D

Step-by-step explanation:

f(x) × g(x) = (3x + 5) × x²

multiply each term in the first factor by x²

= 3x × x² +  5 × x² = 3x³ + 5x² → D

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
