Axis of symmetry
The axis of symmetry of a parabola is a vertical line that passes through the vertex and divides the parabola into 2 congruent parts.
The axis of symmetry can be observed below:
Axis of symmetry: x = 3.
Draw and state the zeros
The zeros are the points at which the parabola crosses the x-axis.
The zeros are shown below:
The zeros are the points (2, 0) and (4, 0).
Draw and state the y-intercept
The y-intercept is the point at which the parabola crosses the y-axis.
The y-intercept can be seen in the figure below:
The y-intercept is the point (0, -8).
State the direction of opening of the parabola
As can be observed in the figures above, the parabola opens downward.
Draw and state the vertex
The vertex is the point of maximum or minimum of the parabola. In this question, it is a maximum point.
The vertex can be observed below:
The vertex is the point (3,1 ).
Max or Min value
The function has a maximum value which is its y-vertex and has a value of 1.
