Q. Let h(x)=log(x).Note: Here, we are referring to log base 10.Find h′′(x).Choose 1 answer:(A) −x21(B) −ln(10)log(x)(C) −x2ln(10)1(D) log(x)
Differentiate h(x): Differentiate h(x)=log(x) with respect to x to find the first derivative, h′(x). Using the derivative of the logarithm function, we have: h′(x)=dxd[log(x)]=xln(10)1
Find first derivative: Differentiate h′(x) to find the second derivative, h′′(x). We need to apply the derivative to h′(x)=xln(10)1. This is a quotient, so we can use the quotient rule or recognize it as the derivative of a reciprocal function. h′′(x)=dxd[xln(10)1]=dxd[ln(10)x−1] Since ln(10) is a constant, we can differentiate x−1 with respect to x: h′′(x)=−1×x−2/ln(10)
Find second derivative: Simplify the expression for h′′(x).h′′(x)=−x2ln(10)1This is the simplified form of the second derivative of h(x).
