Given:
Given that the graph of f(x) was shifted 1 unit up to form the graph of h, let's select the graph which shows the graph of h.
We have the graph of f(x) below:
Apply the transformation rules for functions.
After a shift 1 unit up, the function for h will be:
Hence, after a shift one unit up of f(x), the graph will be:
Therefore, the correct graph is Graph C.
