Partial sums are unbounded. let f: r r be defined by f(x)= min(|x|, x-1) then f is (a) a discontinuous function. (b) continuous and differentiable everywhere. (

partial Sums are unbounded. Let f: R R be defined by f(x)= min(|x|, x-1) Then f is (A) a discontinuous function. (B) Continuous and differentiable everywhere. (C) differentiable everywhere except at one point (D) differentiable everywhere except at two points.
