Disprove the following by providing a counterexample in each case. (a) If a and b are of opposite parity, then 2a + 3b is odd. (b) If x is a real number, then (x + 1)2 > 0.

L9 - 10 An important property of continuous functions is the Intermediate Value Theorem (IVT): Suppose f is continuous on [a,b]ad M is any number between f(a)and f(b), then y=f(x) Corollary....
