Use the function f(x)=|x+4|â2, and its transformation t(x)=|4x+4|â2, to answer the question.
Which statement correctly describes the transformation that maps f to t?
A The mapping statement is f(x)âf(4x), so the vertex will move left by four units, and the transformed function will be wider.
B The mapping statement is f(x)â4f(x) , so the vertex will move left by three units, and the transformed function will be wider.
C The mapping statement is f(x)â4f(x), so the vertex will move right by four units, and the transformed function will be narrower.
D The mapping statement is f(x)âf(4x), so the vertex will move right by three units, and the transformed function will be narrower.
