Question

encontrar derivada f(x)=(3x+5)3−5x en x=2

Answer 1

Respuesta:

f(x) = (3x+5)3-5x

f(x) = 9x+15

f ' (x) = d/dx [ 9x+15 -5x ]

f ' (x) = d/dx [ 4x ] + d/dx [ 15 ]

f ' (x) = d/dx [ 4x ] + 0

f ' (x) = 4×d/dx [x]

f ' (x) = 4(1)

f ' (x) = 4

f ' (2) = 4

R// f ' (2) = 4 es la derivada de f(x) = (3x+5)3-5x en x = 2.
