From the given graph, let's identify the function which represents the graph.
The graph is the graph of a square root function.
Now, apply the parent function of a square root function:
We can see the parent function starts from the origin.
Comparing the given graph with the graph of the parent function, we can see there a shift 3 units to the left.
Now, apply the transformation rule for functions.
After a translation 3 units left, we have:
Therefore, the function represented by the graph is:
