Answer:
Step-by-step explanation:
( -1, 14 ) and (9, 14) notice the y coordinate is the same and the distance between points is 10 (from -1 to 0 is 1 and from 0 to 9 is 9 , 1+9 =10)
The axis of symetry is in the middle between the points so is at
x= (9- 10/2) = 9-5 =4
x=4
point (2, 2), vertex (5, -2.5), equation y= a(x-h)²+k
where h=5, k= -2.5, x=2, y=2 so substitute
2= a( 2-5)² -2.5
2= 9a -2.5
2+2.5 = 9a
4.5/9 =a
0.5 = a
