Dynamic Visualization of Core Exponential and Logarithmic Functions: Graphs and Mapping Diagrams
$f(x)=exp_b(x)= b^x$
$g(x)= log_b(x)$
- Move the $b$ slider to change the value of $b$.
- Uncheck a box to remove that function's graph and mapping diagram.
- Notice the
connection between $b$ and the general features of the functions.
- Select the point $x$ in the mapping diagram to move the point
by mouse or use the scroll up or down key to move the $x$ by
increments of 0.1.
- Move the $y_{zoom}$ slider to change the scale on the target axis of the mapping diagram.
