Answer to Problem 23WE
Explanation of Solution
Given information: The given inequality is:
Calculation: The given inequality is:
The corresponding equation is:
Graph of equation
Put
Which is true, therefore the open half plane containing the origin is graph of given inequality.
Draw as a dashed line because the inequality
Put
Which is false, therefore the open half plane does not contain the origin is graph of given inequality.
Draw as a dashed line because the inequality
Thus the common shaded region is the graph of all inequality.
