# Help with Graphing Rational functions quiz please?

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?

A)k > 0 moves the graph to the left, k < 0 moves the graph to the right.

B)Vertical stretch by a factor of absolute value of k

C)k > 0 moves the graph up, k < 0 moves the graph down.

D_k > 0 reflects the graph across the y-axis.

3. If the parent function is y equals 1 divided by x, describe the change in the equation y equals 5 divided by x.
