The function shown in the graph is shifted 4 units up to produce a new graph.
which function represents the new graph?

First of all, observe that the graphed function is .

Now, if we want to shift the graph 4 units up, it means that we want each point on the graph enlarge its y coordinate by 4: we no longer want to associate

but

And since , we want to map

And in our case, , so the answer is

what is all that apply?
