Answer:
Are we supposed to look at a picture of the graph bec if we are I don’t see it
Step-by-step explanation:


Using hit and trial, you van find it pretty easily-
- Putting x=0, we get y=-3
- Putting x=1, we get y=-1
- Putting x=2, we get y=5
You can try it for yourself as well, for me, I couldn't find any other option appropriate.
I don’t know all of it but....
Axis of symmetry is x=5
Vertex changed to (5,8)
Parabola opens down
$8 x 5 = 40
40/100 = 0.4
$8 + 0.4 = $8.4
Therefore Samantha now earns $8.4 per hour.
$21.60 - $18.00 = $3.60
$3.60 : $18.00 = 0.2
0.2 · 100% = 20%
