# Function Calculator

The calculator will find the domain, range, x-intercepts, y-intercepts, derivative, integral, asymptotes, intervals of increase and decrease, critical points, extrema (minimum and maximum, local, absolute, and global) points, intervals of concavity, inflection points, limit, Taylor polynomial, and graph of the single variable function. The interval can be specified. Parity will also be determined.

Enter a function of one variable:
Enter an interval:
Required only for trigonometric functions. For example, [0, 2pi] or (-pi, oo). If you need oo, type inf.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

## x-intercepts

$$\left(0,0\right)$$$$$\left(3,0\right)$$$

## Critical Points

$$\left(x, f \left(x \right)\right)=\left(0,0\right)$$$$$\left(x, f \left(x \right)\right)=\left(2,-4\right)$$$

## Global (Absolute) Minima and Maxima

For global minima and maxima, see extrema calculator.

## Concave downward on

$$\left(-\infty, 1\right)$$\$

## Derivative

For derivative, see derivative calculator.

## Integral
