The graph of the function f(x)=log 9(x) is stretched vertically by a factor of 4, reflected over the x-axis, reflected over the y-axis, and shifted up by 7 units.

Which of the answer choices gives the equation of the function g(x) described above?

Select the correct answer below:

 
g(x)=4log9(x)−7
 
g(x)=4log9(−x)+7
 
g(x)=4log9(x)+7
 
g(x)=−4log9(−x)+7
 
g(x)=−4log9(−x)−7
 
g(x)=−4log9(x)+7
