Graphing calculator FAQ
Which expressions can this online graphing calculator plot?
It supports x, exponents, parentheses, pi, e, and common functions such as sin, cos, tan, sqrt, abs, log, and ln.
Can I graph more than one function at the same time?
Yes. You can plot up to three functions together, hide or show each one, and compare them on the same coordinate plane.
Does this graphing calculator upload my equations?
No. The graph is calculated in your browser, so equations and downloaded SVG files stay on your device.
How can teachers use this for accommodations?
Teachers can use the adjustable window, color-coded functions, and exportable graph to create clearer visual supports for algebra and pre-calculus lessons.
