select it.
(4) Drag the selected expression to the Graph window.
• This graphs y = x 2 – 1. This graph reveals that
the x -intercepts are x =
±1.
Tip
• As can be seen in the above example, a graph can be drawn when you drop an expression in the
form of f (
x
) into the Graph window. In the case of the 3D Graph window, the expression must be
in the form of f ( x , y ).
• For more information about the Graph window, see Chapter 3. For more information about the 3D
Graph window, see Chapter 5.
