Question

F(x) = x2 – 25 and g(x) = x + 5Step 3 of 4: Find (f. g)(x). Simplify your answer.Answer(f.8)(x) =

Answer 1

Given the functions:

`\begin{gathered} f(x)=x^2-25 \\ g(x)=x+5 \end{gathered}`

Find the product of f.g:

`(f\cdot g)(x)=(x^2-25)\cdot(x+5)`

Multiply both polynomials term by term:

`(f\cdot g)(x)=x^3+5x^2-25x-125`

The expression above cannot be simplified, thus it's the final answer.
