Using Graphs and Logarithms to Solve Problems (Part 2) (1)

This GeoGebra example demonstrates how to solve problems involving logarithms by analyzing and comparing graphs on the same coordinate plane. It highlights the key visual idea that intersection points of appropriately defined functions correspond to solutions of the underlying equation or constraint. The main mathematical concepts include logarithmic functions, their domain and monotonicity behavior, and using graphing (rather than purely algebraic manipulation) to interpret and approximate solutions. In the construction workflow, the example relies on on-canvas instructional objects (text1 and text2) to label what learners should observe—such as which curves to compare and how to read the solution from the graph—together with the standard graphing setup to visualize the relevant functions. Suitable for upper-secondary to introductory college learners, especially for lessons on logarithms, graph-based problem solving, and introductory modeling with function graphs.
