Parabolas Quiz

Parabola = A U-shaped curve where any point is at an equal distance from a fixed point (focus) and a fixed straight line (directrix) Graph = A visual representation of data Focus = A fixed point on a parabola Directrix = A fixed straight line perpendicular to the axis of symmetry of a parabola

Vertex = The highest or lowest point on a parabola Axis of Symmetry = A line that divides a parabola into two equal halves Concave Up = A parabola that opens upwards Concave Down = A parabola that opens downwards

Vertex = The point where the parabola reaches its maximum or minimum value Axis of Symmetry = A line that divides the parabola into two symmetrical halves Directrix = A line that is equidistant from all points on the parabola Focus = A point that is equidistant from the vertex and the directrix

<p>y = x^2 = Opens upwards y = -x^2 = Opens downwards y = (x-1)^2 = Vertex at (1,0) y = 2x^2 = Narrower than the standard parabola</p> Signup and view all the answers

<p>Focus = A fixed point inside the parabola Directrix = A fixed line outside the parabola Axis of Symmetry = A line that divides the parabola into two symmetric parts Vertex = The highest or lowest point on the parabola</p> Signup and view all the answers
