Which is the graph of arctan(x)?

The graph of arctan(x) is second graph.
We have inverse function [tex]y=tan^{-1} x[/tex]
Creating the table
x 0 π/4 π/2 -π/2 -π/3 π/3
y 0 1 ∞ -∞ -√3 √3
From the given graphs we see that the second graph satisfies the values.
So, the correct graph for arctan(x) is second graph.
