Domain: all real numbers

Range: all real numbers

#### Explanation:

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

(Any number in the domain that you put into the function yields an output-- the y value.)

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

The graph below displays the graph of

Since the graph passes through each x and y at one point, the domain and range of the function are "all real numbers," meaning that you can put any number x (
