# In Problems 1-6, find the second derivative. 3.   g ( x ) = x 3 − 1 x

To determine

To calculate: The second derivative of the function g(x)=x31x.

Explanation

Given Information:

The function is g(x)=x31x.

Formula used:

According to the power rule, if f(x)=xn, then,

f(x)=nxn1

According to the property of differentiation, if a function is of the form g(x)=cf(x) then,

g(x)=cf(x)

According to the property of differentiation, if a function is of the form f(x)=u(x)+v(x), then,

f(x)=u(x)+v(x)

The derivative of a constant value, k, is

ddx(k)=0

Calculation:

Consider the provided function,

g(x)=x31x

Rewrite the function using 1an=an,

g(x)=x3x1

To find the first order derivative, differentiate both sides with respect to x,

g(x)=ddx(x3x1)=ddx(x3)ddx(x1)
