Multiple Choice

The graph of the function $f ( x ) = x ^ { 2 } - 11 x + 7$ has been stretched horizontally by a factor of 2 . Find the function for the transformed graph.

A) $g ( x ) = \frac { x ^ { 2 } - 11 x + 7 } { 2 }$
B) $g ( x ) = 2 x ^ { 2 } - 22 x + 14$
C) $g ( x ) = \frac { x ^ { 2 } - 22 x + 28 } { 4 }$
D) $g ( x ) = 4 x ^ { 2 } - 22 x + 7$
