(NOTE: This includes a correction to my earlier solution. My earlier solution overlooked the "minus" in -4. The translation, therefore is down, not up!)

In general,
  • if f(x) = g(x-h), then the graph of g is the graph of f translated h units to the right. And since (x+h) = (x-(-h)), g(x+h) is translated k units to the left.
  • If f(x) = g(x) + k, then the graph of g is the graph of f translated k units up. And g(x) - k is translated k units down.
  • These effects are independent of each other. So if f(x) = g(x-h) + k is translated h units to the right and k unit up.

So the graph of root%283%2C+x%2B2%29+-4 will be the graph of root%283%2C+x%29 translated 2 units to the left and 4 units down. (D)
