A unimodal permutation of length n is an arrangement of the numbers 1 through n in such a way that the numbers increase up to a point and decrease after that and each number is used exactly once. For example: (2, 3, 5, 6, 4, 1) is a unimodal permutation of length 6. (3, 6, 7, 5, 4, 2, 1) is a unimodal permutation of length 7.

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
