You can put this solution on YOUR website! Find an equation for the parabola shown in the figure.
V(-4,3) P (2,2)
----
Assuming that V is the vertex and P is a point on the parabola,
Form: y = a(x-h)^2 + k
Solve for "a" using V and P:
2 = a(2+4)^2+3
2 = 36a + 3
a = -1/36
----
Equation:
y = (-1/36)(x+4)^2 + 3
