Understanding Function Graphing

Graphing mathematical functions is fundamental to understanding relationships between variables in fields like physics, engineering, and economics. Visualizing functions helps identify properties like roots, asymptotes, and periodic behavior.

How to Use This Calculator

Enter a JavaScript math expression using x as the variable
Set appropriate X and Y axis ranges to capture important features
Click "Plot Function" to generate the graph
Hover over points to see coordinate values

Examples to Try

Linear: 2*x + 1
Quadratic: Math.pow(x,2)
Exponential: Math.exp(x)
Trigonometric: Math.sin(x)

Function Type	Example	Typical Range
Linear	2x + 1	X: [-10,10], Y: [-20,20]
Quadratic	x²	X: [-5,5], Y: [0,25]
Trigonometric	sin(x)	X: [-6.28,6.28], Y: [-1.5,1.5]

Tips & Warnings

• Division by zero will create discontinuities in your graph

• Extremely large ranges may cause performance issues

• Complex functions may require more sampling points for accuracy
