30Shifting a graph f(x−3)+1
The graph of y = f(x) passes through (2, 5). Which point must lie on the graph of y = f(x − 3) + 1? A) (−1, 6) B) (5, 4) C) (5, 6) D) (−1, 4)
The point (5, 6), answer C, must lie on the new graph. The shift x−3 moves the point right by 3 (so x goes from 2 to 5), and the +1 moves it up by 1 (so y goes from 5 to 6).
