How does the value of H and K of quadratic function affect the image position

The formula y = a (x + H) ² + k is usually called vertex formula. It clearly reflects the relationship between the vertex coordinates of quadratic function and the independent variables and functions. H and K are the abscissa and ordinate of the vertex respectively. The sign of H determines the position of the axis of symmetry on the X axis. The absolute value of H determines the distance from the axis of symmetry to the Y axis
