$$f{\left(x \right)} = \left(- \frac{21 x}{25} - 3\right) + \left(\left(\sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)}\right) + \log{\left(x \right)}\right)$$
f = -21*x/25 - 3 + sin(x) + sin(10*x/3) + log(x)
Gráfico de la función
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:
$$\left(- \frac{21 x}{25} - 3\right) + \left(\left(\sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)}\right) + \log{\left(x \right)}\right) = 0$$
Resolvermos esta ecuación
Solución no hallada,
puede ser que el gráfico no cruce el eje X
o sea hay que resolver la ecuación:
$$\left(- \frac{21 x}{25} - 3\right) + \left(\left(\sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)}\right) + \log{\left(x \right)}\right) = 0$$

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
$$\cos{\left(x \right)} + \frac{10 \cos{\left(\frac{10 x}{3} \right)}}{3} - \frac{21}{25} + \frac{1}{x} = 0$$

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
$$\left[85.743967650719, \infty\right)$$
Convexa en los intervalos
$$\left(-\infty, -89.5624139330734\right]$$
Asíntotas horizontales
Hallemos las asíntotas horizontales mediante los límites de esta función con x->+oo y x->-oo
$$\lim_{x \to -\infty}\left(\left(- \frac{21 x}{25} - 3\right) + \left(\left(\sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)}\right) + \log{\left(x \right)}\right)\right) = \infty$$
Tomamos como el límite
es decir,
no hay asíntota horizontal a la izquierda
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la derecha:
$$y = \lim_{x \to \infty}\left(\left(- \frac{21 x}{25} - 3\right) + \left(\left(\sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)}\right) + \log{\left(x \right)}\right)\right)$$
$$\lim_{x \to -\infty}\left(\left(- \frac{21 x}{25} - 3\right) + \left(\left(\sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)}\right) + \log{\left(x \right)}\right)\right) = \infty$$

True
Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la derecha:
$$y = \lim_{x \to \infty}\left(\left(- \frac{21 x}{25} - 3\right) + \left(\left(\sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)}\right) + \log{\left(x \right)}\right)\right)$$
Asíntotas inclinadas
Se puede hallar la asíntota inclinada calculando el límite de la función sin(x) + sin(10*x/3) + log(x) - 21*x/25 - 3, dividida por x con x->+oo y x ->-oo
$$\lim_{x \to -\infty}\left(\frac{\left(- \frac{21 x}{25} - 3\right) + \left(\left(\sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)}\right) + \log{\left(x \right)}\right)}{x}\right) = - \frac{21}{25}$$

es decir,
ecuación de la asíntota inclinada a la izquierda:
$$y = - \frac{21 x}{25}$$

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:
$$\left(- \frac{21 x}{25} - 3\right) + \left(\left(\sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)}\right) + \log{\left(x \right)}\right) = \frac{21 x}{25} + \log{\left(- x \right)} - \sin{\left(x \right)} - \sin{\left(\frac{10 x}{3} \right)} - 3$$
- No
$$\left(- \frac{21 x}{25} - 3\right) + \left(\left(\sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)}\right) + \log{\left(x \right)}\right) = - \frac{21 x}{25} - \log{\left(- x \right)} + \sin{\left(x \right)} + \sin{\left(\frac{10 x}{3} \right)} + 3$$
- No
es decir, función
no es
par ni impar
Pues, comprobamos:

- No
es decir, función
no es
