Equation of Parabola using its Vertex and a Point.
Original question text:
A parabola has vertex (3,4) and contains the point (-2,19).
What is the equation of the parabola?A: y = 2/5(x - 3)^2 + 4B: y = 3/5(x - 3)^2 + 4C: y = 3(x - 3)^2 + 4D: y = 15(x - 3)^2 + 4How can Algebrator help you with this problem?

Finding the Equation of a Parabola using its Vertex and a Point is one of the many tasks available on the Wizard menu.
An example using your data is described below.
You must first start by entering the Vertex and the Point.
We will need to use the following formula:
Y = a(x-h)^2+k
An explanation can be obtained by clicking on the "Explain" button
In order to solve this linear equation we need to group all the variable terms on one side, and all constant terms on the other.
