4. Consider the following function in R" f(Fi, n)=-1) k-1 Find the critical point of this function and show whether it is a local minimum, a local maximum, or neither 5. By examining the Hessian matrix, show that if f(x,y, ) has a local minimum at then g(z, y,) -f(x,y, ) must have a local maximum at that point. Likewise, show that if f has a local maximum, then g must have a local minimum at that point. (ro, yo,...

O GRAPHS AND FUNCTIONS Determining whether two functions are inverses of each other For each pair of functions f and g below, find f(g(x)) and g(x)). Then, determine whether f and g are inverses of each other. Simplify your answers as much as possible. (Assume that your expressions are defined for all x in the domain of the composition. You do not have to indicate the domain.) X x - 3 = (b) f(x) 6 2 g(x) = 6x =...
Question 2 please Exercise 1. Define an operation on Z by a b= a - b. Determine ife is associative or commutative. Find a right identity. Is there a left identity? What about inverses? Exercise 2. Write a multiplication table for the set A = {a,b,c,d,e} such that e is an identity element, the product is defined for all elements and each element has an inverse, but the product is NOT associative. Show by example that it is not associative....
