Given the parabola To find the intersections with the xaxis, set y = 0 because any point on the xaxis has zero as its yvalue So the equation to solve then becomes Solve this by getting rid of the 4 on the right side by adding 4 to both sides On the right side the 4 and the 4 cancel each other when they are addedLet's take a look at the first form of the parabola f (x) = a(x −h)2 k f ( x) = a ( x − h) 2 k There are two pieces of information about the parabola that we can instantly get from this function First, if a a is positive then the parabola will open up and if a a is negative then the parabola will open downFocus at (—1, 0), directrix x = 1 4 Focus at (0, —5), directrix y = 5 Focus at (0, 2), directrix y — Elaborate Examine the graphs in this lesson and determine a relationship between the separation ofthe focus and the vertex, and the shape of the parabola Demonstrate this by finding the relationship between p for a vertical
