Answer: Vertical translation of 3 units.
Step-by-step explanation:
Since when a function translated k units vertically then , then the new function becomes H(x)=h(x)+k.
We are given that f(x) = |x| and g(x) = |x| + 3 .
That means the graph of f(x) is translated by 3 units vertically .
Hence, the translation applied to get the graph of g(x) from the graph of f(x) is "Vertical translation of 3 units."
Furthermore it can be seen by the graph below.
