Two possible equations are $y=5$ and $y=x$. Domain of $y=5$: all real numbers Range of $y=5$: the number 5 Domain of $y=x$: all positive integers Range of $y=x$: all positive integers
Work Step by Step
The first five data points have y values that are close to 5. The last five data points have y values close to their respective values of x.
