To find the slope of the quadratic function

3.Choose the function whose point of intersection with the currently selected function you wish to find.

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

Tap on the screen near the intersection, and

repeat from step 2. The coordinates of the intersection nearest to where you tapped are displayed at the bottom of the screen.

We will now find the slope of the quadratic function at the intersection point.

1.Tap to re-display the menu, tap and select Slope.

The slope (that is, the gradient) of the function at the intersection point is displayed at the bottom of the screen.

You can press <

or >to trace along the curve and see the slope at other points. You can also press =or \to jump to another function and see the slope at points on it.

2.Press to re-display the Plot menu.
