The Graph of the Function $f ( x ) = x ^ { 2 } - 11 x + 7$

question 18

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) \(g ( x ) = 4 x ^ { 2 } - 22 x + 7\)
