Graph the Parabola"F" is the focus point This is a Negative Parabola

. Graphing the Parabola y = ax^2 + bx + c

1. Determine whether the parabola opens upward or downward.

a. If a > 0, it opens upward. b. If a < 0, it opens downward.

2. Determine the vertex.

a. The x-coordinate is. b. The y-coordinate is found by substituting the x-coordinate, from Step 2a, in the equation y = ax2 + bx + c.

3. Determine the y-intercept by setting x = 0. 4. Determine the x-intercepts (if any) by setting y = 0, i.e., solving the equation ax^2 + bx + c = 0. 5. Determine two or three other points if there are no x-intercepts.

__**//Graphing the parabola is connect to the other topics by...//**__ *The vertex form has the vertex in it so it is easy to graph,
 * Writing the equation of the parabola makes it easy to graoh also,
 * Vertex to the Standard form, the eqations are equal so the graph will be equal.
 * You would rather graph in vertex for becaue the vertex form is already given.
