The point at which a function or model changed from being concave to convex or vice versa are referred to as ------ point inflection 3. Another name for the second order condition is the -------- condition sufficiency 4. a function is ------ at x = a if in some small region close to the point the graph of the function lies completely beneath its tangential line concave 5. a -------- optimization is the quest for the best in the midst of available (limited) resources constrained 6. a relative -------- is a point at which any economic model or function as we shall soon observe is at a relative maximum or minimum extrema 7. A variable that is determined within the model is called ------------ variable endogenous 8. The ---------order condition locates the points at which the function, model, or equation is neither risingnor falling, but at a leveled ground first 9. The 2nd-order partial, when estimated at the critical point, must both be --------- negative 10. a point on the function or the equation graph where its first derivative is always zero is called the -------- point critical
