81. у = х^2 - 4х + 5
1. 1) у(-3) = (-3)^2 - 4 • (-3) + 5 = 9 + 12 + 5 = 26
2) у(-1) = 1 + 4 + 5 = 10
3) у(0) = 5
4) у(2) = 4 - 8 + 5 = 1
2. 1) х^2 - 4х + 5 = 1
х^2 - 4х + 4 = 0
(х-2)^2 = 0
Х = 2
2) х^2 - 4х + 5 = 5
х^2 - 4х = 0
х(х-4) = 0
х1 = 0 ; х2 = 4
3) х^2 - 4х + 5 = 10
х^2 - 4х -5 = 0
х1 = -1
х2 = 2
4) х^2 - 4х + 5 = 17
х^2 - 4х - 12 = 0
х1 = -2
х2 = 6
83. 1) х є |R
2) х є |R
3) х - 3 ≠ 0
х ≠ 3
4) 5 - х ≠ 0
-х ≠ -5
х ≠ 5
5) 6 - х >= 0
-х >= -6
х <= 6
6) 1/(х+7) >= 0
х + 7 ≠ 0
=>
х + 7 > 0
х > -7
