(a) If b is a positive constant and x > 0, find the critical point of f(x) = x ? bln(x). Your answer will be in terms of b.

(a) If b is a positive constant and x > 0, find the critical point of /(x) = x - bin(x) . Your answer will be in terms of b. X = (b) Use the second derivative test to determine whether the critical point is a local maximum, local minimum, or neither. O local maximum O local minimum O neither
