Which equation represents the transformation formed by horizontally stretching the graph of f(x)=x√ by a factor of 4 and then vertically shifting the graph 2 units down?
Responses

g(x)=4x√−2
g left parenthesis x right parenthesis equals 4 square root of x minus 2

g(x)=4x−2−−−−−√
g left parenthesis x right parenthesis equals square root of 4 x minus 2 end root

g(x)=14x−−−√−2
g left parenthesis x right parenthesis equals square root of 1 fourth x end root minus 2

g(x)=4x−−√−2
