To write: a system of inequalities represented by given graph.
Answer to Problem 21E
Explanation of Solution
Given Information: a graph is given as follows-
Here the dotted line crosses the y-axis at (0, 3). So its equation is given by
This line divides the plane into two parts, first is that where origin lie and second is that where origin doesn’t lie.
The region which contains origin is given by
Now the darked line crosses the x-axis at (-1, 0). So its equation is given by
This line also divides the plane into two parts, first is that where origin lie and second is that where origin doesn’t lie.
The region which contains origin is given by
Hence the shaded region is given by set of inequalities
