(a)

To determine

## To Explain: The natural logarithmic function.

Expert Solution

### Explanation of Solution

The natural logarithmic function is denoted as ln x which equals the logarithmic function with base e.

That is, loga(x)=ln(x) where e is a constant or Euler’s number e2.71828183 .

(b)

To determine

Expert Solution

### Explanation of Solution

A logarithm with base 10 is said to be a common logarithm which is defined as, log10(x)

(c)

To determine

Expert Solution

### Explanation of Solution

Graph:

The natural logarithm function is, y=lnx and the nature exponential function is, y=ex .

Use online graphing calculator and obtain the graphs of the functions y=lnx and y=ex as shown in the Figure1. From Figure1, it is observed that the graphs are reflection of each other about the line y=x .
