# Calculadora de Pontos Críticos e Extrema

## Encontre pontos críticos e extremos passo a passo

A calculadora tentará encontrar os pontos críticos (estacionários), os máximos e mínimos relativos (locais) e absolutos (globais) da função de variável única. O intervalo pode ser especificado.

Enter a function of one variable:
Enter an interval:
Required only for trigonometric functions. For example, (-2pi, 3pi) or [pi/2, 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.

Your input: find the local and global minima and maxima of $f=x e^{- x}$

### Critical Points

$\left(x, f \left(x \right)\right)=\left(1,e^{-1}\right)\approx \left(1,0.367879441171442\right)$

### Global (Absolute) Minima

No global minima.

### Global (Absolute) Maxima

$\left(x, f \left(x \right)\right)=\left(1,e^{-1}\right)\approx \left(1,0.367879441171442\right)$

No local minima.

### Local Maxima

$\left(x, f \left(x \right)\right)=\left(1,e^{-1}\right)\approx \left(1,0.367879441171442\right)$
