Which is the graph of arctan(x)? On a coordinate plane, a function approaches x = negative StartFraction pi Over 2 EndFraction, has an inflection point at (0, 0), and approaches x = StartFraction pi Over 2 EndFraction. The function repeats at increments of pi on the x-axis.
On a coordinate plane, a function approaches y = negative StartFraction pi Over 2 EndFraction, has an inflection point at (0, 0), and approaches StartFraction pi Over 2 EndFraction.

On a coordinate plane, a function approaches the y-axis in quadrant 1, has an inflection point at (StartFraction pi Over 2 EndFraction, 0), and approaches x = pi. The function repeats at increments pi on the x-axis.

On a coordinate plane, a function approaches y = pi, has an inflection point at (0, StartFraction pi Over 2 EndFraction), and approaches the x-axis in quadrant 1.
