Graph natural log of 8

Problem

ln(8)

Solution

1. Identify the expression as the natural logarithm of the constant 8.

2. Evaluate the numerical value using the property that e≈2.718 Since e2≈7.389 and e3≈20.086 the value of ln(8) is slightly larger than 2.

3. Calculate the decimal approximation, which is ln(8)≈2.079

4. Graph the value as a horizontal line y=ln(8) if it is treated as a constant function, or as a single point (8,ln(8)) on the graph of the parent function ƒ(x)=ln(x)

Final Answer

ln(8)≈2.079
