**Title:** Karl's Function Plotter

**Description:**
Karl's Function Plotter is an interactive tool in which functions can be entered and the resulting graph displayed.
**Under the Read Me it describes the following restrictions:
"Usage Restrictions: Plotting graphs is computationally intensive. To limit the burden on the internet service provider for Karl's Calculus Tutor, you will be restricted from plotting another graph after you've plotted one for 3 minutes after plotting a small, 5 minutes after plotting a medium, 12 minutes after plotting a large, 20 minutes after plotting an extra large, and 40 minutes after plotting a huge. Tiny plots incur no delay, so you can use them to preview what the larger plot will look like. So enter your fields carefully before clicking the Plot Now button. Note that if you get an error when you attempt to plot, you will not be delayed in trying again."

**Standard(s): **

[MA2013] AL1 (9-12) 22: Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line). [A-REI10]

[MA2013] AL1 (9-12) 23: Explain why the *x*-coordinates of the points where the graphs of the equations *y* = *f*(*x*) and *y* = *g*(*x*) intersect are the solutions of the equation *f*(*x*) = *g*(*x*); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where *f*(*x*) and/or *g*(*x*) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.* [A-REI11]

[MA2013] AL1 (9-12) 24: Graph the solutions to a linear inequality in two variables as a half-plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes. [A-REI12]

[MA2013] ALT (9-12) 27: Explain why the *x*-coordinates of the points where the graphs of the equations *y* = *f*(*x*) and *y* = *g*(*x*) intersect are the solutions of the equation *f*(*x*) = *g*(*x*); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where *f*(*x*) and/or *g*(*x*) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.* [A-REI11]
