Do not complete #2 if it is not precise enough. thank you allot. math 30-1, transformation

the transformation of Y= f ( x ) to Y= f ( q x ) is a A. horizontal strech by a factor of u B. horizontal strech by a factor of 4 C. vertical strech by a factor of i D. vertical strach by a factor of 4 2. Compared to the function y= f ( x ), the function y = - 5f ( x) can be described as the result of a refledion in the ? 30 Iff the point ( 1, 2) lies on the graph of Y=f ( *) then they y coordinate of the corresponding point on the graph of the transformed function y = 2f ( 4x) is _
