Verified Answer :

The question is asking to choose among the following choices that is the computed value or function of f(x).g(x) and base on the functions and choices, I would say that the answer would be x3 8x2 11x − 20 x3 9x2 19x − 20.  I hope you are satisfied with my answer and feel free to ask for more 

Answer:

\(f(x) \cdot g(x)=x^3+8x^2+11x-20\)

Step-by-step explanation:

let \(f(x) = x^2+3x-4\) and  \(g(x)=x+5\)

Now we find f(x) times g(x)

Replace f(x) and g(x) and then multiply it

\(f(x) \cdot g(x)=(x^2+3x-4)(x+5)\)

Multiply each term inside the second parenthesis

\(f(x) \cdot g(x)=x^3+5x^2+3x^2+15x-4x-20\)

Now combine like terms

\(f(x) \cdot g(x)=x^3+8x^2+11x-20\)
