Question

Известно что y=0,25x-5/6. Сравните: 1) y(-1) и y(0) 2) y(4) и y(-8)

Answer 1

y=0,25x−

6

5

1)

begin{lgathered}y(-1) = -0,25 - frac{5}{6} = -frac{1}{4} - frac{5}{6} = -frac{3}{12} - frac{10}{12} = -frac{13}{12} = -1frac{1}{12}\\y(0) = 0 - frac{5}{6} = -frac{5}{6}\\y(-1)

2)

begin{lgathered}y(4) = 1 - frac{5}{6} = frac{1}{6}\\y(-8) = -2 - frac{5}{6} = -2frac{5}{6}\\y(4)>y(-8)end{lgathered}

y(4)=1−
