I need help with this qouestion.

Consider the function f (,y) = 15 22 4372 43+y The function f (I, y/) has only one critical point, find that critical point. Note: Give the exact answer but not the decimal approximation, for example, write the critical point as (1/2,-5/2) istead of (0.5,-2.5) The critical point is = Select the correct answer. O The critical point is a local maximum O The critical point is a local minimum O The critical point is a saddle point
