Logarithms are also useful when thought of as realvalued functions, or as inverse functions of the corresponding exponential functions. The functions with bases greater than 1 3xand 10x are increasing, while those with bases less than 1 1 3 x and 1 10 x are decreasing. In grades 912, the mathematics curriculum should include the continued study of data analysis and statistics so that all students can construct and draw inferences from charts, tables, and graphs that summarize data from realworld situations.
