For the parabola \(y=(x+6)(x-4)\) determine the coordinates and nature of its turning pont and the equation of the axis of symmetry. The roots are \(x=-6\) and \(x=4\). The aixs of the symmetry is ...

Even functions have graphs that take the y-axis as the axis of symmetry. The odd function has a graph with the origin O as the center of symmetry. Not every function can be defined as even or odd.

The coordinates of the turning point and the equation of the line of symmetry can be found ... by a squared term is 0, which means that the turning point of the graph \(y = x^2 –6x + 4\) is ...

where a, b, and c are numerical constants and c is not equal to zero. Note that if c were zero, the function would be linear. An advantage of this notation is that it can easily be generalized by ...
