Question

Finding the domain, and range from the graph of a rational functionPart (b) only

Answer 1

Domain

The domain of the function is the set of all possible values of x.

Since there is a vertical asymptote at x=3, the domain of the function is:

`(-\infty,3)\cup(3,\infty)`

Range

The range of the function is the set of all possible values of y.

Since there is a horizontal asymptote at y=1, the range of the function is:

`(-\infty,1)\cup(1,\infty)`
