We have a quadratic function written in standard form. This kind of equation can give us a lot of information about the parabola by observing the values of and We see that for the given equation and These values will give us information about the parabola.
Consider the point at which the curve of the parabola changes direction.
The point at which the graph of a parabola changes direction also defines the maximum or minimum point of the graph. Whether the parabola has a minimum or maximum is determined by the value of
