Chapter 8, Problem 28CCSR

To determine

ToFind : The inequalities of given graph.

Answer to Problem 28CCSR

The inequalities of the graph is $y\ge x$ and $y\le 2x+4$ .

Explanation of Solution

Giveninformation:

  

From the graph

  $\begin{array}{l}x>-4\hfill \\ x<=y<=2\left(x+2\right)\hfill \end{array}$

The line which is below represents the equation 1y1y3 $y=x$ and above equation represent the equation $y=2x+4$ .

For the inequality see the graph, the shaded part is above the $y=x$ line and below the $y=2x+4$ line.

Therefore the inequalities become as follows,

  $y\ge x$ and, $y\le 2x+4$ .
