Find the range of the following functions. 1. Y = x2-5x = 6 (x is greater than or equal to - 3, less than or equal to 2) 2. The absolute value of the difference of y = (x2-2x) + 1

1、 When y = x ^ 2-5x + 6 (- 3 ≤ x ≤ 2) y = (X-5 / 2) ^ 2-1 / 4 x = 2, Ymin = 0, x = - 3, ymax = 30, so the value range is [0,30] two. Y = │ x ^ 2-2x │ + 1, so │ x ^ 2-2x │ when x = 0 or 2, there is a minimum value of 0, so the value range is [1, + ∞]. Y = (x-1) ^ 2, X ≥ 2 or X ≤ 0y = - (x

The Red Star store sells a certain kind of clothes at a reduced price of 8 yuan per piece. After 50 pieces are sold, how does the price change compared with the same amount of clothes sold at the original price
I don't miss a word of the title, mainly because I don't understand the title. Hee hee, please=^_ ^=）

Selling the same amount of clothes at the original price makes 50 * 8 = 400 yuan more than when the price is reduced
