What is the vertex of #y=9(5x-2)^2+3#?

1 Answer

The vertex form is written as #y = a(x - h)^2 + k#, where the a value determines the direction of opening (if a > 0, then it opens upwards and if a < 0, then it opens downward); h represents the x-coordinate of the vertex; k represents the y-coordinate of the vertex; x and y represent the x- and y-coordinates of a point on the parabola, other than the vertex.

Hence in our case we write this as
