Please help me to solve the following question:

Show that the curve y = x*ln(2x-3) has no stationary point in the 
region for which x > 2.

Dear Mr. Lee,

A stationary point is just a place where the derivative dy/dx = 0. If 
you take the derivative and set the result equal to 0, you'll have an 
equation that you can solve for x. Your job is to prove there are no 
solutions for x > 2.
