What is Meant by Vertex Coordinates?

In conic sections, the parabola vertex is a point where the parabola crosses its axis of symmetry. We know that the standard equation of a parabola is y = ax2+bx+c. If the coefficient of the term x2 is positive, the vertex will be in the bottom of the U- shaped curve. If the coefficient of the term x2 is negative, the vertex point will be in the top of the U-shaped curve. The standard equation of the parabola in terms of vertex equation is given by:

 y = a(x-h)2 + k

Determine the coordinates of the vertex for the given parabola equation: y= 3x2+12x -12


Given equation: y= 3x2+12x -12

Here a = 3, b = 12

We know that the formula to find the x- coordinate is given by -b/2a

= -12/2(3)

= -2.

Therefore, x -coordinate is -2

Now, substitute the value of x in the given equation, we get y= -24

Hence, the vertex coordinates (h, k) is (-2, -24)
