Reciprocal Functions
Observe that…
Realization
: “The ____________ a number gets to zero, the
____________ in magnitude the reciprocal becomes.”
Thus, many “math geeks” consider a division by ________ to
represent _______________ (which can be positive, negative, or
both).
For graphs, this means the
xintercepts
on one graph are
_______________to a
vertical asymptotes
on the other.
