Function Value Table

Enter a function of x, an x interval and a step size Δx. The calculator returns the table of values f(x) at every x = xMin, xMin + Δx, xMin + 2Δx, … up to xMax, with non-defined entries clearly marked.

Function Value Table

Tabulate f(x) at evenly spaced x values — useful for sketching by hand.

Frequently asked questions

What is a function table for?

It is the classic way to sketch a graph by hand: tabulate enough points and connect them. The calculator does the arithmetic so you can focus on the shape.

How is undefined output handled?

Whenever f(x) returns NaN or ±∞ — for instance at x = 0 in 1/x — the row is marked 'undefined' instead of giving a misleading number.

Is there a maximum number of rows?

The table is capped at 100 rows. For finer detail, narrow the interval or use the function grapher instead.
