A(-3, -1); B(2, -1), C(2, 3)
You can read the length of AB and BC.
|AB| = 5
|BC| = 4
Use the Pythagorean theorem:

The perimeter:

Y<span> - 2 = 1/2</span><span>(x - (-8). Hope this helps</span>
C
Step-by-step explanation:
This has a U like shape so it a parabola.
Parabola correlate with quadratic functions

Since it Going down, the answer is C -x^2.
I’m sorry if I’m wrong I’d stay safe and let someone anwser tell u but I think 20
