Logarithmic Functions (Graph & Equation Anatomy)

This applet contains 4 sliders you can adjust to see changes in both the graph of a logarithmic function and its corresponding equation. As you change/move a slider (one at a time), take careful note of how both the graph and equation change simultaneously. The blueprint equation used for this logarithmic function is f(x) = c * log_a((x-h)) + k.
