Answer:

y = -\frac{5}{2}x - 1

Step-by-step explanation:

5x + 2y = 12

2y = -5x + 12

y = -\frac{5}{2}x + 6

y = mx + b

4 = -\frac{5}{2} ( -2 ) + b

4 = 5 + b

b = -1

y = -\frac{5}{2}x - 1

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]

Espero te haya ayudado!
