| x|
| 2 - -|
| 8|
f(x) = |10 - x |*sin(7*x)
$$f{\left(x \right)} = \sin{\left(7 x \right)} \left|{10 - x^{- \frac{x}{8} + 2}}\right|$$
f = sin(7*x)*Abs(10 - x^(-x/8 + 2))
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:
$$\sin{\left(7 x \right)} \left|{10 - x^{- \frac{x}{8} + 2}}\right| = 0$$

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:
$$\sin{\left(7 x \right)} \left|{10 - x^{- \frac{x}{8} + 2}}\right| = - \sin{\left(7 x \right)} \left|{\left(- x\right)^{\frac{x}{8} + 2} - 10}\right|$$
- No
$$\sin{\left(7 x \right)} \left|{10 - x^{- \frac{x}{8} + 2}}\right| = \sin{\left(7 x \right)} \left|{\left(- x\right)^{\frac{x}{8} + 2} - 10}\right|$$
- No
es decir, función
no es
par ni impar
Pues, comprobamos:
$$\sin{\left(7 x \right)} \left|{10 - x^{- \frac{x}{8} + 2}}\right| = - \sin{\left(7 x \right)} \left|{\left(- x\right)^{\frac{x}{8} + 2} - 10}\right|$$
- No
$$\sin{\left(7 x \right)} \left|{10 - x^{- \frac{x}{8} + 2}}\right| = \sin{\left(7 x \right)} \left|{\left(- x\right)^{\frac{x}{8} + 2} - 10}\right|$$
- No
es decir, función
