Documenting Logarithmic Decay Models

In your role as a junior lab assistant at a clean-energy research company, you are helping document the procedure for visualizing battery efficiency decay. Your team uses the logarithmic function y=log12xy = \log_{\frac{1}{2}} x to model the performance decay over time. To ensure that new interns can easily recreate the performance graph, you need to write a brief procedural guide explaining the preparation steps.

In your response, recall and describe the two initial mathematical steps required to prepare coordinate points for graphing y=log12xy = \log_{\frac{1}{2}} x before any plotting occurs. Specifically, your explanation must:

  1. State the exact equivalent exponential form of the logarithmic equation y=log12xy = \log_{\frac{1}{2}} x.
  2. Identify which variable (xx or yy) you should select a range of values for first to make calculations straightforward, and explain why this selection order is preferred.
