In this question, we have to write the set of points from -6 to 3 but excluding -2 and 3 as a union of intervals .
For union, we use U.
For the points that we have to exclude , we put parenthesis on there side that is ().
Therefore the required interval form is
As we see that () are used with -2 and 3 . And that's the required interval form .
A parabola ALWAYS has a lowest point like unless it would be upside down.
How to solve:
You would calculate two of the numbers to get the vertex.

Answer:
Step-by-step explanation:
y < 3
<__|__|__|__|__|__°__|__|__|__>
-2 -1 0 1 2 3 4 5 6
Basically, for the number line, there is an open circle on the 3 and the line goes to the left of 3.
