To describe and correct the error in solving the inequality or graphing the solution.
Explanation of Solution
Given information:
Given solution
Given graph
Calculation:
It is required to correct the error in solving the inequality or graphing the solution.
Note that the solution for the compound inequality is correct.
But there is an error in graphing the solution.
The graph should contain all points which are less than -10 and greater than 5.
So, the number line before the point -10 and after the point 5 must be shaded but as observe from the graph, the portion of the number line between these two points is shaded which is wrong.
The correct graph of the solution is shown below:
