We looked at how the area, A, of a rectangular mirror varied
as the length, x, of the mirror varied.
We found that the two variables were linked by the equation
A= x(130-x).
a)Factual is the graph of A against x symmetrical?
b)Conceptual How could you use the coordinates of the points where
the graph cuts the x-axis to find the equation of the axis of symmetry?
Find the equation of the axis of symmetry in this case.
C)Factual How you can use the equation of the axis of symmetry to
find the y-coordinate of the maximum point? Find the y-coordinate of
the maximum point in this case.
D)Conceptual How does the symmetry of a parabola allow us to solve
real-life problems?
