Need with the composition of two rational functions. screenshot is below

We just have to write one function inside the other:

Since we have a fraction with x in the denominator, we have to remove from the domain the value of  that makes null the denominator. Thus,

Furthermore, we also have to remove the value of x that annuls the denominator of g(x), because that's the first function that we use. So:

Hence, the domain is:

hope this .
