Vertex
What is the coordinates of the vertex while it is in vertex form?
(h,K)
The standard from of a quadratic equation.
What is Ax2 + Bx + C = 0?
What is the a and b value in the equation
y=-3x^2+4x-7
a= -3 b=4
When x = 3, solve y = x2
The formula to find the x value of the vertex from standard form
What is -b/2a ?
The axis of symmetry from
y=x^2+2x+5
What is x = -1.
When x = 4, solve y = x2 + 5
The y intercept from y = 3x2 + 12x - 1
What is -1?
What is the a and b value in
y=x^2-4
a = 1 b = 0
When x = 2, solve y = x2 + 3x - 1
How is the vertex form written?
y = (x-h)^2 +k
What are the steps when graphing in standard form?
1) FInd axis of symmetry
2) Use x -value to find the y value for the vertex
3) Plot vertex
4) find other point and reflect across the aos
What is the axis of symmetry in
y=-1/2x^2+4x-6
What is x = 4.
When x = -2, solve y = 3x2 - 4x + 5
Another name for x intercepts
Roots
How does one find the coordinates of the vertex when a quadratic is written in factored form?
(p+q) / 2 will find x value then plug in to find y
What are the roots to the factored form:
y = 2 (x+4) (x-1)
What is x=1,-4
What is the axis of symmetry in
y=-2x+4
There is no axis of symmetry.
When x = -1, solve y = -x2 + 3x - 8
What is -12?
The direction of the graph when a is negative versus when a is positive
What is downward versus upward?
