Question

In the following exercises, use the graph of the function to find its domain and range. Write the domain and range in interval notation.

Short answer

The domain of the given function is$(-\infty ,\infty )$and range of the given function is$[2,\infty )$.

Step-by-step solution

Domain of the given function.

To find the domain of the given function look at the graph and find all the value of the$x$that have a corresponding value on the graph. Domain of the this function is$(-\infty ,\infty )$.

Range of the given function.

To find the domain of the given function look at the graph and find all the value of the $y$that have a corresponding value on the graph. Range of the this function is
