The abc's of parabolas
My so called Quadratic Life
100
The parabola with equation y = x^2 has a vertex at this point on the graph.
What is the origin?
100
This is a vertical line that goes through the vertex of a parabola.
What is the axis of symmetry?
100
This is the point that is symmetrical to (- 1, 3) in the parabola having vertex ( 0 , 4).
What is ( 1, 3) ?
100
The a value is this when the parabola has a minimum.
What is positive?
100
This famous arch represents the gateway to the west and resides in the city with the same name
What is the St. Louis Arch?
200
This is where the vertex of parabola lies when there is one solution (or zero.)
What is the x-axis.
200
If the vertex of a line at (2,-4), then the equation for the axis of symmetry would be this.
What is x = 2
200
This is the point the parabola crosses the vertical axis.
What is the y-Intercept?
200
When crossing the Y-axis this value tells you where.
What is C?
200
This strange force of attraction causes everything to fall in a parabolic curve.
What is gravity?
300
This is where the vertex of a parabola lies when its equation has no "b" AND no "c".
What is the origin?
300
This is the equation for the axis of symmetry for the parabola with equation y = x^2 + 4x - 12.
What is x = - 2?
300
The distance from any point on the parabola and its mirror image are this?
What is the same?
300
If a where this, well, then you wouldn't have a quadratic anymore.
What is zero?
300
When you climb to the top of a mountain, you have reached its peak, but it terms of parabolas, you will have reached this.
What is the vertex or maximum.
400
The cute expression -b/2a represents this part of a parabola.
What is the axis of symmetry.
400
This is the equation of the axis of symmetry for the parabola having equation y = 3x^2 + 6x - 3.
What is x = - 1?
400
This is the number of solutions a parabola has if its vertex is in the third quadrant and it is downward facing.
What is zero?
400
a is negative when the graph opens down but, in terms of this, it is up.
What is concave up?
400
This restaurant thinks parabolas are so nice they used them twice, in their logo that is.
What is McDonald's
500
This is the way that you find the y-value of the vertex.
What is substitute the x-value (-b/2a) into the equation?
500
This is the equation for the axis of symmetry for the parabola whose equation has no "b" and no "c".
What is x = 0?
500
This is the numbers of possible solutions for a quadratic function.
What is 0, 1, 2?
500
take your b value, make it negative, then divide it by 2a to get this.
What is the axis of symmetry?
500
You call your parents mom and dad but you call the parent of a quadratic function this.
What is y = x^2
