To write the equation of the quadratic function in vertex form given the vertex \( V(-9, 9) \) and a point \( P(4, -498) \) that lies on the function, we start with the vertex form of a quadratic function:
Here, \( (h, k) \) is the vertex of the parabola. Given the vertex \( V(-9, 9) \), we have:
Next, we use the point \( P(4, -498) \) to find the value of
. We substitute
and \( f(x) = -498 \) into the equation:
Simplify inside the parentheses:
Now, solve for
:
Now that we have the value of
, we can write the equation of the quadratic function in vertex form:
So, the equation of the quadratic function in vertex form is:
