\[y = 2 - 4x\]
\[x\] | \[0\] | \[1\] |
---|---|---|
\[y\] | \[2\] | \[- 2\] |
\[1)\ x = 1 \Longrightarrow \ y = - 2\]
\[x = 0 \Longrightarrow \ \ y = 2\]
\[x = - 2 \Longrightarrow \ \ y = 10\]
\[2)\ y = - 4 \Longrightarrow \ \ x = 1,5\]
\[y = - 2 \Longrightarrow \ \ x = 1\]
\[y = 2 \Longrightarrow \ \ x = 0\]
\[3)\ y < 0\ \ при\ \ x > 0,5.\]
