need help solving this problem.
1. (25 pts) Here's a neat theorem. Suppose that f la, b] [a, b] is continuous; then f will always map some s-value to itself (a so-called fixed point): i.e. 3 c E (a, b) for which f(c)-c (a) Give a "visual proof" of this theorem. Hint: take your inspiration from our "visual proofs" of Theorem 15 and IVT And notice here that the domain and range of f are the same interval; this...

tried ratio test for 2a, but if x = 0, rhe proof doesn't
work.
Thanks a lot.

please solve 22.1, using the Theorem given. Thank you.
Theorem 22.1. Suppose that n people (n 2 2) are at a party. Then there exist at least two people at the party who know the same number of people present First you need to know the rules. We will assume that no one knows him- or herself. We will also assume that if x claims to know y, then y also knows x. The idea behind the proof is this,...
