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 $$$f=\sqrt{4 - x^{2}}$$$

Critical Points

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

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

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

Global (Absolute) Minima

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

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

Global (Absolute) Maxima

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

Local Minima

No local minima.

Local Maxima

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