Vertex of the parabola:
This is the highest(or lowest) point on the parabola.
The vertex is (4;80)
The vertex represents the turning point and the maximum (or minimum) points on a parabolic function.
The zeros are found at (0;0) and (8;0). They are the points on the graph where the height is equal to zero.
The axis of symmetry will be a straight line in the form of x = c.
Axis of symmetry: x = 4
The axis of symmetry runs through the vertex and divides the parabola into two equal halves. This means that each zero of the function is the same distance away from the axis of symmetry.
