Example ELF.DSEQ.E.0. Dynamic
Views for solving an equation $f(x) = Ab^{kx} = C$ on Graphs and
Mapping Diagrams
Work in Progress.
When $k = 1$ this equation has the solution $x = \log_b( \frac C A)$.
When $k \ne 1$ the equation can be solved so that $x = \frac 1k \log_b( \frac C A)$.
Comments: You can move the (red) point
labelled x on the left axis of the mapping diagram to a position where
the arrow head points to $f(x) = C$.
Check the box and the diagram will show the solution.
You can use the sliders to investigate other examples by changing the
base, $A,h$, and $k$, as well as the point $C$ on the target axis.
