Gráfico de la función
Dominio de definición de la función
Puntos en los que la función no está definida exactamente:
$$x_{1} = 0$$
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:
$$\frac{2^{x} \log{\left(2 \right)}}{\left(2^{x} - 1\right)^{2}} + \frac{\left(-1\right) \frac{1}{x \log{\left(2 \right)}}}{x} = 0$$
Resolvermos esta ecuación
Solución no hallada,
puede ser que el gráfico no cruce el eje X
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/(x*log(2)))/x + (2^x*log(2))/(2^x - 1)^2.
$$\frac{\left(-1\right) \frac{1}{0 \log{\left(2 \right)}}}{0} + \frac{2^{0} \log{\left(2 \right)}}{\left(-1 + 2^{0}\right)^{2}}$$
Resultado:
$$f{\left(0 \right)} = \text{NaN}$$
- no hay soluciones de la 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
$$- \frac{2 \cdot 2^{2 x} \log{\left(2 \right)}^{2}}{\left(2^{x} - 1\right)^{3}} + \frac{2^{x} \log{\left(2 \right)}^{2}}{\left(2^{x} - 1\right)^{2}} + \frac{\frac{1}{x} \frac{1}{\log{\left(2 \right)}}}{x^{2}} + \frac{1}{x^{3} \log{\left(2 \right)}} = 0$$
Resolvermos esta ecuación

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:

Puntos de flexiones
Hallemos los puntos de flexiones, para eso hay que resolver la ecuación

Además hay que calcular los límites de y'' para los argumentos tendientes a los puntos de indeterminación de la función:
Puntos donde hay indeterminación:
$$x_{1} = 0$$

$$\lim_{x \to 0^-}\left(\frac{6 \cdot 2^{3 x} \log{\left(2 \right)}^{3}}{\left(2^{x} - 1\right)^{4}} - \frac{6 \cdot 2^{2 x} \log{\left(2 \right)}^{3}}{\left(2^{x} - 1\right)^{3}} + \frac{2^{x} \log{\left(2 \right)}^{3}}{\left(2^{x} - 1\right)^{2}} - \frac{6}{x^{4} \log{\left(2 \right)}}\right) = \frac{\log{\left(2 \right)}^{3}}{120}$$
$$\lim_{x \to 0^+}\left(\frac{6 \cdot 2^{3 x} \log{\left(2 \right)}^{3}}{\left(2^{x} - 1\right)^{4}} - \frac{6 \cdot 2^{2 x} \log{\left(2 \right)}^{3}}{\left(2^{x} - 1\right)^{3}} + \frac{2^{x} \log{\left(2 \right)}^{3}}{\left(2^{x} - 1\right)^{2}} - \frac{6}{x^{4} \log{\left(2 \right)}}\right) = \frac{\log{\left(2 \right)}^{3}}{120}$$
- los límites son iguales, es decir omitimos el punto correspondiente

Intervalos de convexidad y concavidad:
Hallemos los intervales donde la función es convexa o cóncava, para eso veamos cómo se comporta la función en los puntos de flexiones:
Cóncava en los intervalos
$$\left[-3.95948798497865, 3.95948798497865\right]$$
Convexa en los intervalos
$$\left(-\infty, -3.95948798497865\right] \cup \left[3.95948798497865, \infty\right)$$
Asíntotas verticales
Hay:
$$x_{1} = 0$$
Asíntotas horizontales
Hallemos las asíntotas horizontales mediante los límites de esta función con x->+oo y x->-oo
$$\lim_{x \to -\infty}\left(\frac{2^{x} \log{\left(2 \right)}}{\left(2^{x} - 1\right)^{2}} + \frac{\left(-1\right) \frac{1}{x \log{\left(2 \right)}}}{x}\right) = 0$$
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la izquierda:
$$y = 0$$
$$\lim_{x \to \infty}\left(\frac{2^{x} \log{\left(2 \right)}}{\left(2^{x} - 1\right)^{2}} + \frac{\left(-1\right) \frac{1}{x \log{\left(2 \right)}}}{x}\right) = 0$$
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 (-1/(x*log(2)))/x + (2^x*log(2))/(2^x - 1)^2, dividida por x con x->+oo y x ->-oo
$$\lim_{x \to -\infty}\left(\frac{\frac{2^{x} \log{\left(2 \right)}}{\left(2^{x} - 1\right)^{2}} + \frac{\left(-1\right) \frac{1}{x \log{\left(2 \right)}}}{x}}{x}\right) = 0$$
Tomamos como el límite
es decir,
la inclinada coincide con la asíntota horizontal a la derecha
$$\lim_{x \to \infty}\left(\frac{\frac{2^{x} \log{\left(2 \right)}}{\left(2^{x} - 1\right)^{2}} + \frac{\left(-1\right) \frac{1}{x \log{\left(2 \right)}}}{x}}{x}\right) = 0$$
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:
$$\frac{2^{x} \log{\left(2 \right)}}{\left(2^{x} - 1\right)^{2}} + \frac{\left(-1\right) \frac{1}{x \log{\left(2 \right)}}}{x} = - \frac{1}{x^{2} \log{\left(2 \right)}} + \frac{2^{- x} \log{\left(2 \right)}}{\left(-1 + 2^{- x}\right)^{2}}$$
- No
$$\frac{2^{x} \log{\left(2 \right)}}{\left(2^{x} - 1\right)^{2}} + \frac{\left(-1\right) \frac{1}{x \log{\left(2 \right)}}}{x} = \frac{1}{x^{2} \log{\left(2 \right)}} - \frac{2^{- x} \log{\left(2 \right)}}{\left(-1 + 2^{- x}\right)^{2}}$$
- No
es decir, función
no es
par ni impar
