1) y' = 6x² - x/22) y' = (1(x+2) - (x-3)1) / (x+2)² = (x+2 - x + 3) / (x+2)² = 5 / (x+2)²3) y' = (x-1)² + x2(x-1)1 = (x-1)(2x-2+1) = (x-1)(2x-1) = 2x² - 3x + 1
1) y' = 6x² - x/2
2) y' = (1(x+2) - (x-3)1) / (x+2)² = (x+2 - x + 3) / (x+2)² = 5 / (x+2)²
3) y' = (x-1)² + x2(x-1)1 = (x-1)(2x-2+1) = (x-1)(2x-1) = 2x² - 3x + 1
