Frequently Asked Questions
A critical number of a function f(x) is a value x = c in its domain where f'(c) = 0 or f'(c) does not exist.
It numerically approximates the derivative and uses the bisection method to find roots of f'(x)=0 within the range [-10, 10].
You can use standard arithmetic, ^ for exponent, and functions like sin, cos, tan, log, sqrt, abs, exp. Use * for multiplication.
