Writing an Equation in Vertex Form
pickupchik [31]

We get the value of h and k as 9 and -8

The quadratic function g(x) = a(x - h)^2 + k, if a is  not equal to 0,which means that equation has a quadratic value then it is  said to be in standard quadratic form.

If a is positive, then the graph opens upwards,

If a is negative, then it opens downwards.

The line of symmetry of the quadratic equation  is the vertical line x = h, and the co-ordinate of the point of vertex is (h,k).

We are given the co-ordinate of the vertex point in the question and hence all that is required is to equate it.

Therefore, the values of h and k are 9 and -8 in the given equation in vertex form

You can learn more about quadratic equation in standard form here:
