Parabola Intuition 3 requires that you physically move the focus and directix about on the graph, and over in the Answer space the coordinates of the focus and the equation of the directix are displayed... but displayed incorrectly, in the following cases:

- When any coordinate (x or y) is equal to 1, the number shown is "1000/1001".
- When any coordinate (x or y) is equal to n + 0.5, the number shown is n + 1 (i.e., instead of "y=0.5", we have "y=1").
