the domain from the graph is

**Given information**: consider the graph obtained in part a.,

**Calculation**:

The domain of the function f is all the x-values of the points on the graph, and the range is all the corresponding y -values.

From the graph, the function cuts the y -axis at y = 4 and covers the graph till 0, therefore, the range is

Hence, the domain from the graph is
