7   To find the AOS by hand, use the equation -b/2(a)-3x^2+0+4 a b cIf there is no ----- after the 2nd number than add a 0 in the middleThere is no use for c right now-4/ 2(0)AOS= 0

The coefficient has to be positive for the parabola to open up, and negative for the parabola to open down

Vertex:3x^2+4-b/2(a) -0/2(a)=03(0^2)+40+44(0,4)

Vertex: (0,4)Axis of Symmetry:0Solutions (x Intercept): (-1.1,0) (1.1,0)Y Intercepts:4Domain: All Real NumbersRange:y<0

x y1 1 2 -8 3 -234 -445 -71

Parabola ProjectKylie Hinzp: 5

The underside of the rainbow represents amaximum parabola

Vertex: (4,-11)Axis of Symmetry:4Solution:(0.7,0) (7.3,0)Y intercept:(0,5)Domain: All Real NumbersRange:y > -11

x y1 -22 -7 3 -10 4 -11 5 -10

AOS-b/2(a)x^2-8x+5a b c-8/2(1)-8/24

3x^2+4MAXIMUM

-x^2-8x+5MINIMUM

Vertex by Handy=x^2+5-b/2(a)-(-8)/2(1)8/2=4AOS=4Vertex:y=4^2-8(4)+5y=16-32+5y=-11(4,-11)=vertex

The coefficient has to be negative for the parabola to open up.
