select the solution

Question

Consider the equations:
f(x) = -6x - 1 and g(x) =4x^2
Select the solution for (fg) (x).

A. -6x -1 +4x^2

 

B. -24x^3 - 4x^2

 

C. -24x^2 - 1

 

D. -24x^5

Answer 1

f(x) = -6x - 1 and g(x) =4x^2

 

(fg) (x)

 

f(x)*g(x)= (-6x - 1) (4x^2)

 

             = -24x^3-4x^2  Ans. B
