Linear Programming : Simplex Method in Tableau Form

The following problem is something that needs to be put into tableau iterations, but I'm not sure of my answers on it... I'm catching on slowly, but would like to have something to use to check my work... This is a homework problem, but the homework is graded on participation, not correctness in this distance learning class.

Maximum-Minimum Theorem : Continuity and Bounded Functions

(d) Does the conclusion of the Maximum-Minimum Theorem always hold for a bounded function f : R --> R that is continuous on R? Prove or give a counterexample. (a) Fix a, b E R, a < b. Prove that if f [a, b] -->R is continuous on [a, b] and f(x)&#8800;0 for all x E [a, b], then 1/f(x) is bounded on [a, b]. (b) Find a, b E R, a

Maximum-Minimum Theorem, Limits, Continuity and Function Composition

1) Let f, g be defined on R and let c in R. Suppose that lim f = b and that g is continuous at b. Show that lim g 0 f = g(b) Note: R: real numbers g 0 f means composition of f and g 2) Let A = [0, 1) U (1,2]. Let B = [0, 1] U [2, 3]. Does the conclusion of the maximum-minimum theorem always hold for a function f: A
