Plot y = f(x) over a chosen domain, with an optional second curve.

f(x)

g(x) (optional)

x-min

x-max

f(x) = g(x) = Legend outdated — fix the expression to update.

Tips: use x^2, sin(x), sqrt(x), abs(x), or 1/x.

How it works

A graph of y = f(x) shows how the output changes as the input moves along the horizontal axis. Points are sampled across your chosen domain and connected into a curve.

Pick an expression in x and a domain from x-min to x-max. The grapher samples points across that interval, evaluates the expression at each sample, and connects the resulting y-values into a continuous curve.
The plotted curve is simply those (x, y) pairs in order. An optional second expression draws another curve on the same axes so you can compare shapes, intersections, or relative growth without changing the domain.
