p139, #13g, §2 Solution

Factor is shifted one unit towards the right.

Multiplying by x magnifies it by a factor ranging from 1 to :

Function y(x):

• has an x-extent and a y-extent ;
• behaves asymptotically as for ;
• is monotonous:

  

• has vertical slope at x=1;
• is concave down for smaller x, concave up for larger x;
• the inflection point is at

  

  giving x=4/3.
