Scaling is indicated by graphs of this form:

                               y = a f(x)              y-scaling

                               y = f(ax)               x-scaling

 

Some examples to observe:

 

Graphs of the form y = e^ax

 

                         

 

Graphs of the form y = ae^x

 

                              

 

 

Graphs of the form y = ln ax

 

                                 

 

Graphs of the form y = a ln x
