Step-by-step explanation:
cause i did 22/100 and 50/100 and got these answer one of them might be right or both of them are wrong. This is what i think so.
The attached graph represents the solution set of 
<h3>How to determine the graph?</h3>
The complete options are not given.
So, I would plot the graph that represents the solution set
The inequality is given as:

Start by splitting the inequalities as follows:


The above means that we plot the graphs of f(x) and g(x) to represent the solution set
