Identify Function: Identify the function to differentiate.We are given the function h(x)=2x and we need to find its second derivative, denoted as h′′(x).
Differentiate Once: Differentiate the function once to find the first derivative.The first derivative of h(x) with respect to x is found using the exponential differentiation rule. The derivative of ax, where a is a constant, is ax⋅ln(a).So, h′(x)=dxd[2x]=2x⋅ln(2).
Differentiate Again: Differentiate the first derivative to find the second derivative.Now we need to differentiate h′(x)=2x⋅ln(2) with respect to x.Using the same rule as before, we get h′′(x)=dxd[2x⋅ln(2)]=2x⋅ln(2)2.However, this is incorrect because the constant ln(2) should not be squared. We need to correct this.
