Question 182030
Points are of form:


(x,y) or (x, f(x))



f(x-2) tells you to subtract 2 from each x to get new y, but you need to add 2 to undo this. So add 2 to each x (keep y the same)


New points: 


(5,-1), (3,0), (2,3), (0,4)



-------------------------------------------------


f(2x) tells you to double each x. Need to take half of each x to undo this


New points: 


(1.5, -1), (0.5, 0), (0, 3), (-1, 4)
