Answer : x = 3
The axis of symmetry is essentially a line that splits the function into equal halfs. To to find the axis of symmetry all you have to do is look for the highest or lowest part of the function.
In this case the lowest part is at the coordinates (3,-2).
And the axis of symmetry is the x-coordinate.
So your answer is x = 3.

Answer: -1 < x < 3</h3>
===========================================================
Explanation:
The first thing to do is to swap the positions of the x < 3 and the x > -1
So you'll end up with x > -1 and x < 3
Now focus entirely on x > -1. Swap the left and right sides, and also swap the inequality sign. So we end up with -1 < x
That means the "x > -1 and x < 3" is the same as "-1 < x and x < 3"
From here, we collapse the two inequalities to form the compound inequality -1 < x < 3
We can say "x is between -1 and 3, excluding either endpoint".
