Answer:
B. The lines AB and BC are perpendicular.
Step-by-step explanation:
If all the points are doubled on the x-axis, they are perpendicular.
hope this helps.
The x coordinate stays the same but y coordinate changes sign so it will be a reflection in the x-axis.

Answer:</h3>
f(x) = -(x -2)² +3
<h3>
Step-by-step explanation:</h3>
We can fill in the vertex (h, k) values immediately in the vertex form ...
... f(x) = a(x -h)² +k
To find the value of a, we solve the equation for a at some point other than the vertex. The given point is (0, -1), so we can use that:
... -1 = a(0 -2)² +3
... -4 = 4a . . . . . . . . . subtract 3, simplify
... -1 = a . . . . . . . . . . . divide by 4
Now, we know the function is ...
... f(x) = -(x -2)² +3
