Try It 10.45: Graphing y=log12xy = \log_{\frac{1}{2}} x

To graph the logarithmic function y=log12xy = \log_{\frac{1}{2}} x, the equation can first be rewritten in its equivalent exponential form, (12)y=x\left(\frac{1}{2}\right)^y = x. Then, by selecting a range of values for yy, the corresponding xx-values can be calculated to generate coordinate points. Plotting these points allows for graphing the specific curve of the logarithm with a base of 12\frac{1}{2}.
