How to Use
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.
