Puntos de cruce con el eje de coordenadas Y
El gráfico cruce el eje Y cuando x es igual a 0:
sustituimos x = 0 en 1/(tan(x) + x^5 + 2).
$$\frac{1}{\left(\tan{\left(0 \right)} + 0^{5}\right) + 2}$$
Resultado:
$$f{\left(0 \right)} = \frac{1}{2}$$
Punto:
(0, 1/2)
Extremos de la función
Para hallar los extremos hay que resolver la ecuación
$$\frac{d}{d x} f{\left(x \right)} = 0$$
(la derivada es igual a cero),
y las raíces de esta ecuación serán los extremos de esta función:
$$\frac{d}{d x} f{\left(x \right)} = $$
primera derivada
$$\frac{- 5 x^{4} - \tan^{2}{\left(x \right)} - 1}{\left(\left(x^{5} + \tan{\left(x \right)}\right) + 2\right)^{2}} = 0$$

Intervalos de crecimiento y decrecimiento de la función:
Hallemos los intervalos donde la función crece y decrece y también los puntos mínimos y máximos de la función, para lo cual miramos cómo se comporta la función en los extremos con desviación mínima del extremo:
La función no tiene puntos mínimos
La función no tiene puntos máximos
Decrece en todo el eje numérico
Asíntotas horizontales
Hallemos las asíntotas horizontales mediante los límites de esta función con x->+oo y x->-oo
True

Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la izquierda:
$$y = \lim_{x \to -\infty} \frac{1}{\left(x^{5} + \tan{\left(x \right)}\right) + 2}$$
True

Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la derecha:
$$y = \lim_{x \to \infty} \frac{1}{\left(x^{5} + \tan{\left(x \right)}\right) + 2}$$
Asíntotas inclinadas
Se puede hallar la asíntota inclinada calculando el límite de la función 1/(tan(x) + x^5 + 2), dividida por x con x->+oo y x ->-oo
True

Tomamos como el límite
es decir,
ecuación de la asíntota inclinada a la izquierda:
$$y = x \lim_{x \to -\infty}\left(\frac{1}{x \left(\left(x^{5} + \tan{\left(x \right)}\right) + 2\right)}\right)$$
True

Tomamos como el límite
es decir,
ecuación de la asíntota inclinada a la derecha:
$$y = x \lim_{x \to \infty}\left(\frac{1}{x \left(\left(x^{5} + \tan{\left(x \right)}\right) + 2\right)}\right)$$
Paridad e imparidad de la función
Comprobemos si la función es par o impar mediante las relaciones f = f(-x) и f = -f(-x).
Pues, comprobamos:
$$\frac{1}{\left(x^{5} + \tan{\left(x \right)}\right) + 2} = \frac{1}{- x^{5} - \tan{\left(x \right)} + 2}$$
- No
$$\frac{1}{\left(x^{5} + \tan{\left(x \right)}\right) + 2} = - \frac{1}{- x^{5} - \tan{\left(x \right)} + 2}$$
- No
es decir, función
no es
par ni impar
