Calculadora de pontos de inflexão e concavidade

Encontre pontos de inflexão e concavidade passo a passo

A calculadora tentará encontrar os intervalos de concavidade e os pontos de inflexão da função dada.

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.

Your input: find the inflection points and intervals of concavity of $$$f=x e^{- 5 x}$$$

Inflection Points

$$$\left(x, f \left(x \right)\right)=\left(\frac{2}{5},\frac{2}{5 e^{2}}\right)\approx \left(0.4,0.0541341132946451\right)$$$

Concave upward on

$$$\left(\frac{2}{5}, \infty\right)= \left(0.4, \infty\right)$$$

Concave downward on

$$$\left(-\infty, \frac{2}{5}\right)= \left(-\infty, 0.4\right)$$$
