6. Scaling

Open the Scaling Excel worksheet below, showing horizontal and vertical scaling corresponding to the functions f(kx) and kf(x).

Use the slider to change the value of k and note how the graph and the equation of the function automatically change.

Try different values of k and b …
How does a change in k and b influence the function – what is the relationship between k and the graph and the equation?
