У = -3х + 1
1)
у(-2) = -3 * (-2) + 1 = 6 + 1 = 7
у (2/3) = - 3 * (2/3) + 1 = - 2 + 1 = -1
у (0) = - 3 * 0 + 1 = 1
у (- 0,1) = - 3 * (-0,1) + 1 = 0,3 + 1= 1,3
2)
у=0
- 3х + 1 = 0
- 3х = -1
х = 1/3
у= -2
- 3х + 1= - 2
-3х = - 2 - 1
-3х = -3
х = 1
у= 1/2
- 3х + 1 = 1/2
- 3х = 1/2 - 1
- 3х = -1/2
х = - 1/2 : (-3) = - 1/2 * ( - 1/3)
х = 1/6
у= - 1,1
-3х + 1 = - 1,1
-3х = - 2,1
3х = 2,1
х=0,7
