Question

17) y=-2(x-3)^2+8
Vertex: ____
Y-intercept(plug-in 0): ____

18) y=4x^2-8x-5
a=__ b=__ c=__

1. Circle: Graph upwards/downwards

2.Vertical Axis of Symmetry
X=-b/2a
X=__

3.Vertx (plug in axis of symmetry):

4. Y-intercept (plug in 0):(0,_)

5. X-intercepts (Solve by any method):

X=__,__

6.Graph the equation below:

Answer 1

Answer:

17. vertex (3,8)

y intercepts = -10

18. a=4,b=-8,C=-5

1. graph downwards

2.x=1

3.vertex(1,-9)

4.y intercept = -5

5.x = -1/2 or X = 5/2

Answer 2

17. Vertex (3,8) y-intercept=(0,-10)
18. A=4 b=-8 c=-5 upwards
