About the parabola
It is where the parabola meets the y-axis
What is y-intercept?
The method used to expand a factored equation into a standard equation. For example, the method used to expand (x+1)(x+2)=x2+3x+2
What is the "FOIL" method or algebra tiles or 2-way table?
The y-value of the vertex (i.e. "k" value) of a parabola is also its ________ value.
What is optimal or maximum/minimum?
(h,k) are the coordinates of this point on a parabola
What is the vertex?
The method used to factor a standard equation into its factored form. For example: the method used to factor x2+3x+2 into (x+1)(x+2)
What is the "MAN" method?
If a flying stone has a parabolic trajectory with
h = -0.5 (x-6)2 + 19
where h is its height (in meters) and x is its horizontal distance travelled (in meters).
What is the maximum height of the stone?
What is 19 meters?
The factored form easily shows us
What is zeros?
The factored form of y = x2 +8x + 12
What is y=(x+2)(x+6)?
The term used to describe that a business is neither making nor losing money?
What is break-even?
The standard form, y=ax2+bx+c, easily shows us
What is y-intercept?
The axis of symmetry of the parabola with equation y=(x-1)(x-5)
What is x=3?
If a flying stone has a parabolic trajectory with
h = -0.5 (x-6)2 + 19
where h is its height (in meters) and x is its horizontal distance travelled (in meters).
What is the height when the stone is just thrown?
What is 1 meter?
The parabola is symmetric about this line
What is the axis of symmetry or x=h?
The y-intercept of the parabola with equation y=2(x+1)(x-3)
What is -6?
If a flying stone has a parabolic trajectory with
h = -0.5 (x-6)2 + 19
where h is its height (in meters) and x is its horizontal distance travelled (in meters).
How far away horizontally is the stone when it is 11 meters high?
What is 2 meters away and 10 meters away?
