Finding the Zeros of a Cubic Function Using Function Intersection

Create a new Graph Window.

Input the cubic function and press Enter.

To find the zeros of the cubic identify the intersection of the graph and the x-axis.

Reset the window settings as necessary.

Access the function intersection tool.

Move the pointer to hover over the graph of the cubic and press Enter.

Repeat by moving the pointer to hover over the x-axis and press Enter.

The intersection points are highlighted.

Label the coordinates to find the values for the zeros of the function.
