Find the domain offg. fa)=+1 g) = a all real numbers b. all real numbers, except 0 Call real numbers, except -1 d all real numbers, except 1 Please select the best answer from the choices provided OA OB OC D

Answer 1

In this problem we have that:

`\begin{gathered} f(x)=x^2+1 \\ g(x)=(1)/(x) \end{gathered}`

So now we can make the product f(x)g(x)

`f(x)g(x)=(x^2+1)/(x)`

Now to find the domain of this exprestion we have to make the denominator equal to 0 so:

`x=0`

This means that the domine of the function f(x)g(x) will be all real numbers, except 0
