Graph of any function

Function grapher for class use. Type a function, graph it, and read the apparent domain and range from the current viewing window.

Function y = f(x)

Classroom note: the displayed domain and range are read from the current viewing window and are numerically estimated from the graph. For exact answers, students should still derive the domain/range analytically.

Supported syntax: +, -, *, /, ^, parentheses, and functions such as sin, cos, tan, asin, acos, atan, sqrt, log, exp, abs. Constants: pi, e. Note: log(x) is the natural logarithm (base e). For log base 10 use log(x)/log(10).
