LetA be an invertible matrix. Prove that pinv{A) = A-1

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. (Existence of Zeros) If f(xicnioson[ a,b]dfi f(a) > 0and f(b) < 0 (or f(a) < 0nd f(b) > 0), then f(x)asaoni ( a,b). 1 ex. Does the IVT imply that f(x)= x has a zero on (−1,1)
