WebbNot all parabolas are congruent to the basic parabola. For example, the arms of the parabola $y=3x^2$ are steeper than those of the basic parabola. The $y$-value of each point on this parabola is three times the $y$-value of the point on the basic parabola with the same $x$-value, as you can see in the following diagram. WebbWe start by assuming a general point on the parabola (x,y) (x,y). Using the distance formula, we find that the distance between (x,y) (x,y) and the focus (-2,5) (−2,5) is \sqrt { (x+2)^2+ (y-5)^2} (x +2)2 +(y −5)2, and the distance between (x,y) (x,y) and the directrix y=3 y = 3 is \sqrt { (y-3)^2} (y −3)2. http://emathlab.com/Algebra/Conics/parabolaH.php jeremy combs basketball
