Question

Describe the transformation of y=ln(x) that would give the graph for y=7ln(x)

Answer 1

Vertical Stretch

1) Considering the function y= lnx as the parent function, the reference. When we multiply it by 7 we produce a vertical stretch

2) Visualizing it we have:

3) Hence, we have a Vertical Stretch. In blue: y =7ln(x) and in red y=ln(x)
