Question

1. Which is the graph of--8-7-6-5-4-3-2-1 0 1O-8-7-6-5-4-3-2-1 0 1O--8-7-6-5-4-3 -2 -1 0 1--8-7-6-5-4-3 -2 -1 0 1

Answer 1

Let's solve the inequality first:

`\begin{gathered} (1)/(2)x+2\ge1 \\ x+4\ge2 \\ x\ge-2 \\ or \\ (1)/(2)x+2\leq-1 \\ x+4\leq-2 \\ x\leq-6 \end{gathered}`[tex]\begin{gathered} 4x+2<10 \\ 4x<8 \\ x<2 \\ or \\ 4x+2>-10 \\ 4x>-12 \\ x>-3 \\ -3
