Question 387077
Well, this formula is the x-intercept formula (also known as roots). You can put each set equal to zero to solve for the x-intercepts.
x+3=0    Subtract your 3 over
x=-3

x-2=0  Add your 2 over
x=2

These are your roots, where your parabola is going to hit on the x-axis.
To get the vertex, you take the average of these two numbers. That will give you your x value for your vertex.

2+(-3)=-1/2     x=-1/2    You add the two values and divide by two.
y=(-1/2+3)(-1/2-2)      Plug in the value for x and solve for y. This will give you the y value of vertex
y=(5/2)(-5/2)
y=-25/4 or -6 1/4

So vertex is at (-1/2, -6  1/4) This parabola is opening up because there is no negative out front of parenthesis, and it will cross the x-axis at 2 and -3. This should be enough information to graph this parabola.
