Multiple choice question x = 0 is a function y = arctan1 / X X = 0 is the function y = arctan1 / X A. Removable discontinuities B. Jump breakpoint C. Infinite discontinuity D. Oscillation discontinuity

Multiple choice question x = 0 is a function y = arctan1 / X X = 0 is the function y = arctan1 / X A. Removable discontinuities B. Jump breakpoint C. Infinite discontinuity D. Oscillation discontinuity

When x approaches 0, 1 / x approaches infinity
Arctan1 / X tends to Pai / 2
Therefore, the discontinuity point can be removed
