Online Graphing Calculator
Plot functions the easy way — no confusing menus.
Type your function, and the graph appears instantly. Zoom, pan, and trace coordinates, just like the graphing screen on a TI-84. Free, with nothing to install.
Click the calculator, then type on your keyboard — digits, + − * / ^ ( ) work, Enter calculates.
A graphing calculator without the learning curve
Real TI-84s are powerful, but graphing on one means pressing Y=, then WINDOW, then GRAPH, then TRACE — and hoping you set the window right. Here, you just type the function. The graph draws itself.
Each function gets its own color, so comparing y = x^2 and y = 2x + 1 is easy. When you want to look closer, the zoom buttons and drag-to-pan do the rest. It feels natural on a phone screen.
Graphing tips that actually help
See where two graphs meet
Enter both functions, turn on Trace, and drag slowly. When the y-values match, you have found the intersection point. This is the fastest way to solve systems of equations visually.
Fix a blank graph with the window
If your graph looks empty, your window is probably wrong. A function like y = x^2 + 100 will not show up in the default −10 to 10 view. Widen Ymax and try again.
Use parentheses generously
Type 1/(x+2), not 1/x+2 — they are different functions. When in doubt, add parentheses. The calculator follows the normal order of operations.

When is graphing useful?
Pretty much everywhere in high school math. Algebra 2 uses graphs for quadratics and systems. Pre-calculus adds trig graphs and transformations. Calculus is all about seeing slopes, areas, and limits.
Even if your class does not require a graphing calculator, seeing the picture builds intuition. A parabola makes a lot more sense when you can watch it move as you change the numbers.
