The function f(x) is defined by f( x ) = array*20c | x |x 0, arrayarray*20c ,x 0 x = 0 array . then, at x = 0 it is
Let's break it down: solving fully: apply relevant formula, put numbers, compute. Result comes as Discontinuous at x = 0 and has discontinuity of first kind. Easy verification shows it satisfies condition.
