let f(x) = x2 3x − 4 and g(x) = x 5. find f(x) ⋅ g(x). x3 3x2 16x − 20 x3 5x2 14x − 20 x3 8x2 11x − 20 x3 9x2 19x − 20

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:

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

Step-by-step explanation:

let [tex]f(x) = x^2+3x-4[/tex] and [tex]g(x)=x+5[/tex]

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

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

[tex]f(x) \cdot g(x)=(x^2+3x-4)(x+5)[/tex]

Multiply each term inside the second parenthesis

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

Now combine like terms

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