The domain for f(x) and g(x) is the set of all real numbers.

Let f(x) = 3x + 5 and g(x) = x^2.

Find f(x) • g(x).

a  3x^3 + 5x^2


b    3x^3 + 3x^2 + 5


 c     x^2 − 3x − 5


  d    3x^2 + 5

Respuesta :

If you want to multiply the two functions, the answer is a.


In fact, you have


[tex] (3x + 5)x^2 = 3x \cdot x^2 + 5\cdot x^2 = 3x^3 +5x^2 [/tex]
