3. Select a point on the curve and click to indicate where to start
shading under the function. The direction in which you move next
determines whether the region shaded is on the left, right, or center
of the curve.
4. Select a point on the curve and click to indicate the end boundary of
the shaded area. A region under the function is shaded based on the
points you selected.
You can work with Shade Under Function in the following ways:

shaded area.
– To remove the shading, right-click or
/-click the shaded region
and choose

boundary for shading is set to a plotted value, you can change the
plotted value to update the shading.

starting or ending boundary.
