9
noting that | a | = | - a | = a
The distance between the 2 numbers is
| 14 - 2 | = | 12 | = 12
OR
|2 - 14 | = | - 12 | = 12
--------------------------------------------------------------------
10
The distance between the 2 numbers is
| - 10 - 8 | = | - 18 | = 18
OR
| 8 - (- 10) | = | 8 + 10 | = | 18 | = 18

Answer:
y = -(x -3)^2 +2
Step-by-step explanation:
The vertex form of the equation for a parabola is ...
y = a(x -h)^2 +k
where the vertex is (h, k) and the value 'a' is a vertical scale factor.
The value of 'a' can be found by looking at the y-value of points ±1 either side of the vertex relative to the vertex. Here, the vertex y-value is +2 at x=3, and either side goes down 1 unit (to y=1) for 1 unit to the right or left. So, a = -1.
Using the values we've read from the graph for the vertex (h, k) = (3, 2) and the scale factor a = -1, we can write the equation as ...
y = -(x -3)^2 +2
