sin(x) + cos (x)
f(x) = ----------------
2*x + sin(x)
$$f{\left(x \right)} = \frac{\sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{2 x + \sin{\left(x \right)}}$$
f = (sin(x) + cos(x)^2)/(2*x + sin(x))

Puntos de cruce con el eje de coordenadas X
El gráfico de la función cruce el eje X con f = 0
o sea hay que resolver la ecuación:
$$\frac{\sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{2 x + \sin{\left(x \right)}} = 0$$

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
$$\frac{- 2 \sin{\left(x \right)} \cos{\left(x \right)} + \cos{\left(x \right)}}{2 x + \sin{\left(x \right)}} + \frac{\left(\sin{\left(x \right)} + \cos^{2}{\left(x \right)}\right) \left(- \cos{\left(x \right)} - 2\right)}{\left(2 x + \sin{\left(x \right)}\right)^{2}} = 0$$

Asíntotas horizontales
Hallemos las asíntotas horizontales mediante los límites de esta función con x->+oo y x->-oo
$$\lim_{x \to -\infty}\left(\frac{\sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{2 x + \sin{\left(x \right)}}\right) = 0$$
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la izquierda:
$$y = 0$$
$$\lim_{x \to \infty}\left(\frac{\sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{2 x + \sin{\left(x \right)}}\right) = 0$$
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la derecha:
$$y = 0$$
$$\lim_{x \to -\infty}\left(\frac{\sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{2 x + \sin{\left(x \right)}}\right) = 0$$

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:
$$\frac{\sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{2 x + \sin{\left(x \right)}} = \frac{- \sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{- 2 x - \sin{\left(x \right)}}$$
- No
$$\frac{\sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{2 x + \sin{\left(x \right)}} = - \frac{- \sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{- 2 x - \sin{\left(x \right)}}$$
- No
es decir, función
no es
par ni impar
Pues, comprobamos:
$$\frac{\sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{2 x + \sin{\left(x \right)}} = \frac{- \sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{- 2 x - \sin{\left(x \right)}}$$
- No
$$\frac{\sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{2 x + \sin{\left(x \right)}} = - \frac{- \sin{\left(x \right)} + \cos^{2}{\left(x \right)}}{- 2 x - \sin{\left(x \right)}}$$
