Question 1071429: Use the vertex (h, k)
and a point on the graph (x, y)
to find the general form of the equation of the quadratic function.
(h, k) = (−5, −1), (x, y) = (−7, 3)

Standard Form Equation for a Parabola:

for vertex (h,k)


What about the coefficient, a, in case you also have an included point on the parabola?


-----and you would use your other given point to evaluate a. You were already also given (h,k) vertex.


Do you know what to do now?
( I did not substitute any values for you.)

Student wants further help:
Substituting the values, this happens.

solving for a and substituting the other point's values,

-
Standard Form equation is .
Fully multiply and further arithmetic simplification gives you general form .
