To find the slope of the quadratic function

To find the signed area of the two functions

12.Choose the linear function whose intersection with the quadratic function you wish to find.

The coordinates of the intersection point are displayed at the bottom of the screen.

Note: If there is more than one intersection

(as in our example), the coordinates of the intersection point closest to the current cursor position are displayed.

13.Find the slope of the quadratic function at the intersection point.

Select Slope

The slope value is displayed at the bottom of the screen.

14.To find the area between the two functions in the range –2 x –1, first move the cursor to

F1(x) = 1 – x and select the signed area option.

Select Signed area
