What is parabola?
What are the zeros of the equation x^2 - 3x + 10 ?
Zeros: -2 and 5
Graph the equation. Must include vertex, and at least one point on each side. y=(x-5)(x-1)
What is graph on board?
What are the zeros of the equation y = 2 (x - 5)² + 6
None, it never crosses the x-axis.
The range of any quadratic functions deals with?
The Max or Min
What are the Zeros of the equation -5x^2 +10 x - 5?
Zeros: 1
If the number before the x^2 is 7 . Does the graph has a max or a min? why?
Min. if you graph 7x^2 is a happy face so it has a minimum.
What are the Zeros of the equation y = 2(x-1)(x+7)
Zeros: 1 and -7
Name the x-intercepts y=x^2 - x - 2
What is (-1,0) and (2,0)?
Name the vertex x^2 - 4x - 5 = 0
What is (2,-9)?
The line that runs through the vertex and divides the parabola in half.
What is axis of symmetry?
What are the Zeros of the equation y=x^2+5x+6?
Zeros -2 and -3
Name the x-intercepts. y= (x-1)^2 + 1
What is None?
