Determine en donde la funcion dada es creciente,concava hacia riba y concava hacia abajo. y= x3–3x–1
Minchanka [31]

Answer:

Es creciente en los siguientes intervalos: [-\infty,-1] U [1,\infty]

Es concavo hacia abajo en el intervalo: [-\infty,0)

Es concavo hacia arriba en el intervalo: (0,\infty]

Step-by-step explanation:

Sea la función:

f(x)=x^{3}-3x-1

Para determinar el intervalo de crecimeinto debes determinar la primer derivada de la función (f'(x)). El intervalo donde f'(x) > 0 es creciente.

La derivada de f(x) es:

f'(x)=3x^{2}-3

Entonces es creciente en los siguientes intervalos:

[-\infty,-1] U [1,\infty]    

Ahora para determinar la concavidad debemos determinar la segunda derivada de la función (f''(x)). Si f''(x) > 0 la función es concava hacia arriba, si f''(x) < 0 la funcion es concava hacia abajo.

La segunda derivada de f(x) es:

f''(x)=6x        

Por lo tanto:

Es concavo hacia abajo en el intervalo: [-\infty,0)

Es concavo hacia arriba en el intervalo: (0,\infty]
