Concept explainers
To solve: the inequality with its graph and graph the solution.
Answer to Problem 17E
The required result is
Its graph should have an open point at 2 and a shaded line going to the right of 2 and an open point at -1 and a shaded line going to the left of -1.
Explanation of Solution
Given:
Calculation:
Since the right-hand side of inequality is a negative number, and the inequality symbol used is >, then any number will always be greater than 0 except for 3 which will make the left-hand side equal to the right-hand side. Therefore, its solution is the set of all real numbers except 3.
Its graph should have a shaded line from the left most part of the number line until rightmost part of the number line with an open point at 3.
Conclusion:
Therefore, its solution is the set of all real numbers except 3.
The required result is
