f(x) = --------------
3 2
x - x - 42*x
$$f{\left(x \right)} = \frac{\sin{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)}$$
f = (sin(x)*|x - 7|)/(-42*x + x^3 - x^2)
Gráfico de la función
Dominio de definición de la función
Puntos en los que la función no está definida exactamente:
$$x_{1} = -6$$
$$x_{2} = 0$$
$$x_{3} = 7$$
$$x_{1} = -6$$
$$x_{2} = 0$$
$$x_{3} = 7$$
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:
$$\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)} = 0$$
Resolvermos esta ecuación

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
$$\frac{\sin{\left(x \right)} \operatorname{sign}{\left(x - 7 \right)} + \cos{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)} + \frac{\left(- 3 x^{2} + 2 x + 42\right) \sin{\left(x \right)} \left|{x - 7}\right|}{\left(- 42 x + \left(x^{3} - x^{2}\right)\right)^{2}} = 0$$

$$x_{1} = -6$$
$$x_{2} = 0$$
$$x_{3} = 7$$
$$x_{1} = -6$$
$$x_{2} = 0$$
$$x_{3} = 7$$
Asíntotas horizontales
Hallemos las asíntotas horizontales mediante los límites de esta función con x->+oo y x->-oo
$$\lim_{x \to -\infty}\left(\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)}\right) = 0$$
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la izquierda:
$$y = 0$$
$$\lim_{x \to \infty}\left(\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)}\right) = 0$$
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la derecha:
$$y = 0$$
$$\lim_{x \to -\infty}\left(\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)}\right) = 0$$
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la izquierda:
$$y = 0$$
$$\lim_{x \to \infty}\left(\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)}\right) = 0$$
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la derecha:
$$y = 0$$
Asíntotas inclinadas
Se puede hallar la asíntota inclinada calculando el límite de la función (|x - 7|*sin(x))/(x^3 - x^2 - 42*x), dividida por x con x->+oo y x ->-oo
$$\lim_{x \to -\infty}\left(\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{x \left(- 42 x + \left(x^{3} - x^{2}\right)\right)}\right) = 0$$
Tomamos como el límite
es decir,
la inclinada coincide con la asíntota horizontal a la derecha
$$\lim_{x \to \infty}\left(\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{x \left(- 42 x + \left(x^{3} - x^{2}\right)\right)}\right) = 0$$
Tomamos como el límite
es decir,
la inclinada coincide con la asíntota horizontal a la izquierda
$$\lim_{x \to -\infty}\left(\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{x \left(- 42 x + \left(x^{3} - x^{2}\right)\right)}\right) = 0$$
Tomamos como el límite
es decir,
la inclinada coincide con la asíntota horizontal a la derecha
$$\lim_{x \to \infty}\left(\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{x \left(- 42 x + \left(x^{3} - x^{2}\right)\right)}\right) = 0$$
Tomamos como el límite
es decir,
la inclinada coincide con la asíntota horizontal a la izquierda
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:
$$\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)} = - \frac{\sin{\left(x \right)} \left|{x + 7}\right|}{- x^{3} - x^{2} + 42 x}$$
- No
$$\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)} = \frac{\sin{\left(x \right)} \left|{x + 7}\right|}{- x^{3} - x^{2} + 42 x}$$
- No
es decir, función
no es
par ni impar
Pues, comprobamos:
$$\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)} = - \frac{\sin{\left(x \right)} \left|{x + 7}\right|}{- x^{3} - x^{2} + 42 x}$$
- No
$$\frac{\sin{\left(x \right)} \left|{x - 7}\right|}{- 42 x + \left(x^{3} - x^{2}\right)} = \frac{\sin{\left(x \right)} \left|{x + 7}\right|}{- x^{3} - x^{2} + 42 x}$$
- No
es decir, función
no es
