  1. The graph of y = f (x) is translated 2 units up. What function represents the new graph?
    y = f (x) + 2 y = f (x) − 2 y = f (x + 2) y = f (x – 2)
  2. The graph of f (x)=x² is translated 2 units to the right. What is the vertex of the new graph?
    (0, –2) (0, 2) (–2, 0) (2, 0)
  3. The graph of f (x)= 2x² is reflected over the x–axis. What is the new graph’s axis of symmetry?
    y = 0 x = 2 x = 0 x = –2
