Sample Function Table

For function f(x) = x² - 4 across range [-2, 2] with step 1:

x = -2 → f(x) = 0

x = -1 → f(x) = -3

x = 0 → f(x) = -4

x = 1 → f(x) = -3

x = 2 → f(x) = 0

Calculation Methodology

For each successive x value from start to end by increment step, the mathematical expression is evaluated. Undefined points, such as divisions by zero, are properly identified.

Frequently Asked Questions

Which mathematical operators are supported?

Standard operators (+, -, *, /), exponents (^), roots (sqrt), trigonometric functions (sin, cos, tan), log, and standard constants (pi, e).

What if the step interval is too small?

Very small steps generate large data outputs; choose an interval between 0.1 and 1 suitable for your resolution needs.

How to write powers and products?

Use the asterisk * for multiplication and caret ^ for powers.

Can table outputs be exported?

Yes, results can be copied and pasted directly into spreadsheet programs like Excel or Google Sheets.
