Use our free graphing calculator to evaluate any function f(x) over a range of x values. Enter an expression in terms of x, set the range and step, and get a table of (x, y) points, the maximum and minimum y values, zeros/roots (where f(x)=0), the slope between endpoints, and f(0).
Evaluate any function f(x) over a range. Enter an expression using x as the variable (supports sin, cos, tan, log, ln, sqrt, ^, π, etc.). Set x-min, x-max, and x-step to generate a table of (x, y) points. Also finds the maximum and minimum y values, zeros/roots (where the function crosses the x-axis), and f(0).
