Plot as many as four functions of x on the same Cartesian coordinate system. Choose the visible x and y ranges, compare color-coded curves, and inspect a table of representative values without installing graphing software.
Formula
Enter expressions using familiar notation:
sin(x)
x^2 / 5
sqrt(x + 4)
1 / (x - 2)
The plot samples each function throughout the x window. Use a narrower window when you need more visual detail around an intercept or turning point.
Examples
Compare a wave and parabola
Enter sin(x) on the first line and x^2 / 5 on the second. Their colors in
the legend match their curves and their columns in the value table.
A graph suggests where roots, extrema, and asymptotes are;
use algebra, the derivative calculator, or the integral calculator when you
need a numerical or symbolic result.
