Given the set M = {y | y = x & # 178; - 2x + 3}, n = {y | y = 2x & # 178; - 3x + 1}, then m ∪ n= Search process, online, etc
Find the best value. To do the function problem, you must master the function image, y = x & # 178; - 2x + 3 image opening up, vertex ordinate in [4 × 3 - (- 2 ^ 2)] / 4 point, that is 2, so this function y ≥ 2 (note: ^ represents power) similarly, find the best value of y = 2x & # 178; - 3x + 1, opening up, vertex ordinate - 1 / 8 (coordinate
