first off, the function A is an exponential one with a base of 4
the function B is just a horizontal line at y = 1/4
1) similarities? none other than they have both share the same point of -1, 1/4 or -1, 0.25, so they cross each other at that point, after that, B keeps on going horizontally, and A keeps on going up.
2) related? not sure on that one, I don't see much relation, other than they're both on the same plane and share the same axes.
3) hmmm what is the following again?
