What are the solutions to the system of equations?
*No spaces, write the word "and" inbetween the two points.
Inverses are when a function switches what?
What line does a function and its inverse reflect over?
The inverse of a function is always a function.
What regression equation best models this data?
If the directrix is horizontal, and the focus is above it, what does the parabola look like?
What is the focus of a parabola?
If the focus is (-5, 4) and the directrix is x=1, what is the vertex?
The equation of any parabola is
is the vertex and is the distance between the focus and the vertex. If the vertex is and the focus is , what's the equation of the parabola in this form?Someone kicks a ball from a height of 2 feet at a velocity of 100 feet per second. What is the height of the ball after 6 seconds?
Sometimes
can be negative.If the directrix is vertical and the focus is to the left of it, what does the parabola look like?
If the directrix is vertical and the focus is to the right of it, what does the parabola look like?
If the directrix is horizontal and the focus is below it, what does the parabola look like?
What is the directrix of a parabola?
If the vertex of a parabola is (2, -3) and the focus of the parabola is (2, 1), what is the equation of the directrix?
