Respuesta :

In this problem we have that:

[tex]\begin{gathered} f(x)=x^2+1 \\ g(x)=\frac{1}{x} \end{gathered}[/tex]

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

[tex]f(x)g(x)=\frac{x^2+1}{x}[/tex]

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

[tex]x=0[/tex]

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