Знаменито что y=0,25x-5/6. Сравните: 1) y(-1) и y(0) 2) y(4) и

y=0,25x

1)

\beginlgatheredy(-1) = -0,25 - \frac56 = -\frac14 - \frac56 = -\frac312 - \frac1012 = -\frac1312 = -1\frac112\\\\y(0) = 0 - \frac56 = -\frac56\\\\y(-1)

2)

\beginlgatheredy(4) = 1 - \frac56 = \frac16\\\\y(-8) = -2 - \frac56 = -2\frac56\\\\y(4)gt;y(-8)\endlgathered

y(4)=1
