Question

A graph is translated according to the following rule. Describe the translation.

(x, y) → (x, y +3)

A. The graph is translated 3 units to the left.
B. The graph is translated 3 units up.
C. The graph is translated 3 units down.
D. The graph is translated 3 units to the right.

Answer 1

B. The graph is translated 3 units up.

Answer 2

We are given the original function (x,y) and is asked what transformation happens when it is converted to (x, y+3). In this case, the answer to this problem must have to be B. The graph is C. The graph is translated 3 units down since y is decreased by 3.
