Perform the indicated operations if the given changes are made in the indicated examples of this section.

In Example 6, change the logarithm base to 4 and then make any other necessary changes.

Data from Example 6

For the logarithmic function y = log₂ x,  we have the standard independent variable x and the standard dependent variable y.
If x = 16, y = log₂16,  which means that y = 4, because 2⁴ = 16.
If x = 1/16 , y = log2(1/16), which means that y = −4, because 2⁻⁴ = 1/16.
