1. The following is the graph of the parent function y equals 1 divided by x.

Curve with center at the point (0, 0), going down and to the left through (negative 1, negative 1) and (negative 8, negative 2) and up to the right through (1, 1) and (8, 2).

True or False

2. What affect does "k" have on the parent function y equals 1 divided by x?
