<h2>
Explanation:</h2>
Let's graph the equation:

Which is the red graph shown below. As you can see this is the pattern of the Absolute Value Function. In order to translate this graph 14 units up, let's add 14 to
. In doing so we get the new function:

So we get a new graph which is the blue one. In order to prove that this is the correct translation, let's take the vertex of the red graph which is the origin. To translate this graph 14 units up implies that each point is shifted 14 units up, so for the vertex of the red graph:

So the new vertex matches the vertex of the blue graph. Finally, the equation for the translation of
14 units up is
