### Graphing Functions

Graphs up to 5 functions simultaneously in rectangular coordinates.
How to use   ||   Examples   ||   Other Notes

How to Use
• Enter a function f1(x) in the text input field marked "f1(x)=" (Example: f1(x)=ex)
• Click the "Graph" button (this button also refreshes the graph)
• To see two functions graphed simultaneously:
• Enter the second function f2(x) in the text input field marked "f2(x)="
• Click (to its "on" state) the check box next to this input field
• Click the "Graph" button
(Example: f1(x)=ex and f2(x)=x2)
Up to 5 functions can be graphed simultaneously
• To remove a function from the graph, click (to its "off" state) the check box next to the associated text input field and click the "Graph" button to refresh
• To erase the graph and all input fields, click the "Clear" button
The text input fields can accept a wide variety of expressions to represent functions, and the buttons under the graph allow various manipulations of the graph coordinates.
Examples
 Miscellaneous functions: Parabola: f1(x)=x2 Rational: f2(x)=x/(x+1) Conditional:   f3(x)= x2 if x< 1, else x-2 Exponential: f4(x)=ex Trigonometric: f5(x)=sin(x) Comparison: f1(x)=e-x2 f2(x)=1/(1+x2) Comparison: f1(x)=(ex+ex)/2 f2(x)=x2+1

Other Notes
The graphs of the functions are color-coded, corresponding to the colors of the labels marking the text input fields: the graph of f1(x) is blue, f2(x) is red, f3(x) is green, f4(x) is orange, and f5(x) is magenta.
