[FONT="]I understand how to do the vertical stretches and the translations. However, how will the absolute value of the function come into play? Do I first change all the negative y values to positive like (0,-1) would be (0,1)? [/FONT]

[FONT="]Also, how would the original f(x) graph be transformed with this equation y=|2f(x)-1|. Would the -1 in the equation be a vertical translation of +1 because its absolute value?

Could I get the final points [/FONT]of the transformed graph for each equation? Thanks!
