The Graphing Calculator lets you plot mathematical functions and visualise equations on an interactive graph. Enter one or more functions to see their graphs, identify intersections, and explore mathematical relationships visually.
Type a function of x (e.g. sin(x), x^2 - 4, or 1/x) and the calculator will plot it on a coordinate grid. You can adjust the viewing window to zoom in on areas of interest.

Graphing functions helps visualise mathematical relationships. Key features to look for include roots (x-intercepts), y-intercepts, maxima and minima, asymptotes, and intervals of increase or decrease.
Common function families include linear (y = mx + b), quadratic (y = ax^2 + bx + c), polynomial, rational, exponential, logarithmic, and trigonometric functions. Each has characteristic shapes and properties.
Problema: Graph y = x^2 - 4
Solucion: Enter x^2 - 4. The graph shows a parabola crossing the x-axis at x = -2 and x = 2
Respuesta: U-shaped curve with vertex at (0, -4)
Problema: Compare sin(x) and cos(x)
Solucion: Enter sin(x) as function 1 and cos(x) as function 2
Respuesta: Two waves offset by pi/2, intersecting at x = pi/4 + n*pi
