I need help on this question?

Answer 1

The domain of the function
`f` is all the
`\boxed{x}` values of the points on the graph, and the range is all the corresponding
`\boxed{y}` values. From the graph of
`f`, we see that the domain of
`f` is the interval
`\boxed{(-\infty, \infty)}` and the range of
`f` is the interval
`\boxed{(-\infty, 7)}`.
