At which points do the graph of Y1 and Y2 intersect?
A) (-1, 1) and (1, 5)
B) (1, 3) and (3, 9)
C) (1, 5) and (1, 3)
D) (-1, 1) and (3, 9)

For two graphs to intersect, their y-values must be the same at the same x-value. Choices A, B, and C each have points that do not satisfy this condition for any standard pair of functions. Without the specific equations for Y1 and Y2, we rely on the principle that intersection points must have the same x and y coordinates in both functions, making D the most plausible choice given the information.
