Function graphs — type a formula and move the plot around like a map

The graph of y = f(x) is all points of the plane with coordinates (x, f(x)). For example, for y = x² at x = 2 we get y = 4 — the point (2, 4) lies on the parabola.

It helps to know graphs by sight: y = kx + b — a line, y = x² — a parabola, y = 1/x — a hyperbola, y = sin(x) — a wave, y = √x — half of a sideways parabola.

The points where the graph crosses the X axis are the roots of f(x) = 0. Plot x^2 - 5x + 6 and you will see the parabola cross the axis at 2 and 3 — the same roots the equation solver finds.

You can write: + − * / ^, parentheses, sin cos tan sqrt abs ln log exp, the numbers pi and e. Multiplication can be omitted: 2x, 3sin(x).
