What is the equation of the parabola that has a vertex at # (7, 9) # and passes through point # (3, -2) #?
It is easiest to use the form y = a
In vertex form, the form mentioned above, The vertex is represented by (p, q) and the of your choice is represented by X and Y respectively. In other words you are solving for a in the formula.
-2 = a
-2 = 16a + 9
-2 -9 = 16a
So, the equation would be y =
