Define a Different Viewing Window for Your Graph
Notice in the table that when
by 50 each time increases by 1, you can set the
X
window to see the graph for this domain and range by changing the window values.
To Do This
1. Display the window settings screen.
2. Define the values so that
Xmax = 3, Xscl = 1,Ymin = 150
, and
Ymax = 150
Note: This changes the settings so that:
/ 3 ^ X ^ 3 and / 150
Yscl=50, there is one unit between each tick mark
on the X axis and 50 units between each tick mark
on the Y axis.
3. Graph
Y =50X
1
window.
Note: Remember that each tick mark on the X axis
represents 1 unit, while each one on the Y axis
represents 50. It's always important to know the
scale of your graphs so that you understand the
graph you are viewing.
4. Trace the graph.
Note: Each tick mark on the X axis is 1 and on the
Y axis is 50.
5. Display the
Y
Tip: You can go directly to any coordinate pair on
the graph by entering the value you want.
