Introducing the Parabola
Vertex-The maximum or minimum point on the graph. It is the point where the graph changes direction.
Y-intercepts- The y-intercept is the point on the y- axis where the parabola pass through the y-axis.
Zeros- The zeros are in other words, the x- intercepts. This is the point on the graph where the parabola passes through a point on the x-axis.
Optimal value- The highest or lowest value the graph reaches.
Axis of symmetry- The vertical line that separates the parabola in two equal halves.
