Write the standard form of the equation for the parabola shown in the graph.

now, let's take a peek at the graph, the vertex is at (-3,1) and the focus point is at (-1,1).

so, from x = -3, to x = -1, there are only 2 units, namely the focus point is 2 units away from the vertex, namely that "p" distance is 2 units.  Because the parabola is opening to the right-hand-side, the "p" unit is positive, so p = +2.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
