The Problem Tells by What Factor and Direction the Graph $y = 1 + \frac { 1 } { x ^ { 2 } } \quad$

Multiple Choice

The problem tells by what factor and direction the graph of the given function is to be stretched or compressed. Give an
equation for the stretched or compressed graph.
- $y = 1 + \frac { 1 } { x ^ { 2 } } \quad$ stretched vertically by a factor of 5

A) $y = 1 + \frac { 25 } { x ^ { 2 } }$
B) $y = 5 + \frac { 5 } { x ^ { 2 } }$
C) $y = 1 + \frac { 5 } { x ^ { 2 } }$
D) $y = \frac { 1 } { 5 } + \frac { 1 } { 5 x ^ { 2 } }$
