Answer:
The logarithmic function for x = 2y is written as y = log2 x or f(x) = log2 x. The number 2 is still called the base. In general, y = logb x is read, “y equals log to the base b of x,” or more simply, “y equals log base b of x.” As with exponential functions, b > 0 and b ≠ 1


We have critical points whenever both partial derivatives vanish:



The Hessian is


At (0,0), we have

, so (0,0) is a saddle point.
At (-1, -1), we have

and

, so (-1, -1) is a local minimum.
At (1, 1), we have

and

, so (1, 1) is also a local minimum.
