Explanation of Solution

The natural logarithm is the function given by lnx=1x1tdt,x>0.

The number e is the number in the natural logarithm that satisfies lne=1e1tdt=1.

The derivative ddx(lnx)=1x is positive for x>0, so lnx is an increasing function of x.

The second derivative of lnx is 1x2. It is negative, so the graph of lnx is concave down.

The domain of the function is (0,).

The range of the function is (,).

Sketch the graph of the function y=lnx as shown in Figure 1.

Thomas' Calculus: Early Transcendentals (14th Edition), Chapter 7, Problem 1GYR

Provide the algebraic properties of the natural logarithmic function lnx as follows.

  • lnbx=lnb+lnx
  • lnbx=lnblnx.
  • ln1x=lnx.
  • lnxr=rlnx,r rational.
