Answer: D. the graph of f is translated 3 units up and 7 units to the right.
Given:

For a function notation f(x-c), this means that we need to move horizontally, c units to the right. With this, we know that the graph is translated 7 units to the right.
Then, for the notation f(x) + d, this would mean a vertical translation of d units upward. With this, we know that the graph is translated 3 units up.
With all of these, we know that the graph of f is translated 3 units up and 7 units to the right.
