Solución
Ha introducido
[src]
sin(3*x) x - 1
f(x) = -------- + ------
2*x 2
x - 4
$$f{\left(x \right)} = \frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x}$$
f = (x - 1)/(x^2 - 4) + sin(3*x)/((2*x))
Gráfico de la función
Dominio de definición de la función
Puntos en los que la función no está definida exactamente:
$$x_{1} = -2$$
$$x_{2} = 0$$
$$x_{3} = 2$$
$$x_{1} = -2$$
$$x_{2} = 0$$
$$x_{3} = 2$$
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:
$$\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x} = 0$$
Resolvermos esta ecuación
Solución no hallada,
puede ser que el gráfico no cruce el eje X
o sea hay que resolver la ecuación:
$$\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x} = 0$$
Resolvermos esta ecuación
Solución no hallada,
puede ser que el gráfico no cruce el eje X
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
$$3 \frac{1}{2 x} \cos{\left(3 x \right)} - \frac{2 x \left(x - 1\right)}{\left(x^{2} - 4\right)^{2}} + \frac{1}{x^{2} - 4} - \frac{\sin{\left(3 x \right)}}{2 x^{2}} = 0$$

$$\left[208.916433417059, \infty\right)$$
Crece en los intervalos
$$\left(-\infty, -374.372230951242\right]$$
Asíntotas verticales
Hay:
$$x_{1} = -2$$
$$x_{2} = 0$$
$$x_{3} = 2$$
$$x_{1} = -2$$
$$x_{2} = 0$$
$$x_{3} = 2$$
Asíntotas horizontales
Hallemos las asíntotas horizontales mediante los límites de esta función con x->+oo y x->-oo
$$\lim_{x \to -\infty}\left(\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x}\right) = 0$$
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la izquierda:
$$y = 0$$
$$\lim_{x \to \infty}\left(\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x}\right) = 0$$
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la derecha:
$$y = 0$$
$$\lim_{x \to -\infty}\left(\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x}\right) = 0$$
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la izquierda:
$$y = 0$$
$$\lim_{x \to \infty}\left(\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x}\right) = 0$$
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 sin(3*x)/((2*x)) + (x - 1)/(x^2 - 4), dividida por x con x->+oo y x ->-oo
$$\lim_{x \to -\infty}\left(\frac{\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x}}{x}\right) = 0$$
Tomamos como el límite
es decir,
la inclinada coincide con la asíntota horizontal a la derecha
$$\lim_{x \to \infty}\left(\frac{\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x}}{x}\right) = 0$$
Tomamos como el límite
es decir,
la inclinada coincide con la asíntota horizontal a la izquierda
$$\lim_{x \to -\infty}\left(\frac{\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x}}{x}\right) = 0$$

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:
$$\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x} = \frac{- x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x}$$
- No
$$\frac{x - 1}{x^{2} - 4} + \frac{\sin{\left(3 x \right)}}{2 x} = - \frac{- x - 1}{x^{2} - 4} - \frac{\sin{\left(3 x \right)}}{2 x}$$
- No
es decir, función
no es
par ni impar
