Hi i have a problem with the following questions
1-The graph of f(x)=√(x) is compressed horizontally by the factor 1/2, reflected in the y axis, and translated 3 units right and 2 units down. Also sketch a graph.
My answer was F(x)= √(-2x+6)-2 however the answer from the book is F(x)= -√(2x-6)-2
2-The graph of y=1/x is stretched vertically by the factor 3 , reflected in the x-axis and translated 4units left and 1 unit up.
My answer was -3y=(1/x+4)+1 however the answer from the book is y=(-3/x+4)+1
which one is right?
Thank you in advance
