Explanation:
The blue shaded region describes any x value that is smaller than -3, or that is equal to -3. We can phrase it as "x is less than or equal to -3". Therefore, that's why we go for
If you graphed , without the "or equal to" portion, then you would have an open circle at the endpoint. The open circle means we don't include that value as part of the solution set.
Answer: See the graph attached.
Step-by-step explanation:
1. To solve this exercise you must plot the points given in the table of the problem, which are shown below:
(-4,1), (0,2), (3,3)
2. You must plot the first value of each ordered pair on the x-axis.
3. You must plot the second value of each ordered pair on the y-axis.
4. Therefore, when you plot them, you obtain the graph shown attached.
