If f is a function defined on the real line, we may obtain the graph of g(x)=f(4x+7) from the graph of f by: ...?
Since the +7 is inside the parenthesis, it moves left and right. A plus with left and right means left! 4x means the slope is 4 times more steep. Therefore, the graph would be moved to the left 7 units and would be at a slope that is four times higher per horizontal movement.
I tried that answer (it's online homework), and it didn't accept it. Is there any other way it can be transformed that way?
