WOverdrawing Built-in Function Graphs ~: of,
You can draw two or more built-in function graphs on the same screen. Ther range of first
graph is set automatically, and the same range is. applied for subsequent graphs. The
important thing to note in the following example is the use of (2). By pressing &a) before
] to graph the second function, you are telling the unit to leave the previously drawn
graphs on the display. If you do not press Eq), the unit will clear the graphic display auto-
matically and graph only the last function you entered.

\ GHA) FS)(CLS) 8)

Fi}(snh) Ee)
GalF2)(csh) EES
Note | b
You cannot use built-in function graphs in multistatements (page 35) and programming.
WGraphing Manually Entered Functions
You can graph manually entered functions by simply pressing Ga) and then entering the
function. Remember that you also have to specify range parameters (page 153).
