Is #z = xy# an inverse variation?

Answer 1
# z = xy# is an inverse variation on #x# and #y#; that is for a fixed value of #z# multiplying one of #x# or #y# by any value #k# will result in the other being divided by #k#
#z = xy# is a direct variation on #x# and #z#.
#z= xy# is (also) a direct variation on #y# and #z#.

Answer 2

No, z = xy is not an inverse variation. Inverse variation occurs when one variable increases while the other decreases, or vice versa. Inverse variation is represented by the equation y = k/x, where k is a constant.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
