Domain and range of real functions
Type your function in the box. Some examples: x^2 for [math]x^2[/math], exp(x) for [math] e^x[/math], sqrt(x+1) for [math]\sqrt {x+1}[/math], abs(x) for [math]|x|[/math], ln(x) for [math]\ln(x)[/math], 1/(x^2+1) for [math]\frac{1}{x^2+1}[/math][br]The [color=#0a971e]green[/color] horizontal line represents the domain. The [color=#1551b5]blue[/color] vertical line represents the range. Press Shift to Zoom with mouse.
