To create a table of values for graphing a logarithmic function, you typically want to find corresponding values of \( x \) by plugging in different values of \( y \) into the logarithmic equation. This allows you to generate points that can be graphed on the coordinate plane.
Thus, the correct option is:
**B. Plug in y-values to the logarithmic equation to find the corresponding x-values.**
This means you take a logarithmic function of the form \( y = \log_b(x) \) and for various values of \( y \), calculate the corresponding \( x \) values by rewriting the logarithmic equation in its exponential form: \( x = b^y \).
Thus, the correct option is:
