Math Solver / Graphing Calculator
Graphing Calculator
Plot one or several functions, find intercepts, then drag and zoom to explore.
Press Enter to solve · ^ for powers · sqrt() for roots · separate a system with a comma

The graphing calculator plots functions of x instantly. Enter one function or several separated by commas — x^2 - 4 or sin(x), cos(x) — and read the x- and y-intercepts under the graph.
How to use the graphing calculator
- Type a function. “y =” is optional.
- Add more functions with commas to compare them.
- Drag the graph to move around; scroll or use + and − to zoom.
What to look for on a graph
- x-intercepts (roots) — where the curve crosses y = 0; these solve f(x) = 0.
- y-intercept — the value f(0).
- Intersections — where two curves meet solve f(x) = g(x).
- Asymptotes — lines the graph approaches, as with 1/x.
Common function families
| Family | Example | Shape |
|---|---|---|
| Linear | 2x + 1 | Straight line |
| Quadratic | x^2 – 4 | Parabola |
| Exponential | 2^x | Rapid growth |
| Trigonometric | sin(x) | Repeating wave |
| Rational | 1/x | Two branches with asymptotes |
Questions about graphing
Can I graph an equation like y = 2x + 1?
Yes. Type y = 2x + 1 or just 2x + 1.
Does it work on a phone?
Yes. Drag with one finger to pan and use the + and − buttons to zoom.
Can it graph inequalities?
Use the inequality solver, which solves the inequality and graphs the related function.
