+
x
– 3) you want to graph.
4. Press
6
(DRAW) to graph the function.
• This will display a graph screen. Since the graph intersects the
x
-axis at –1.5 and 1,
we can conclude that the solution (
x
= 1) obtained in step
4
is valid. The –1.5 value
was not included as a solution because we specified a lower limit of 0.
• The graph drawn here is stored in the strip we created in step
5
