Question

Example of function which is sectionally continuous

Answer 1

$\bold{Example:}$ The function f(x) = signum(x) is sectionally continuous on [-1, 1], but the function g(x) = 1/x is not sectionally continuous on that interval.

$\bold{Example:}$ The function x is (even) continuous, but not sectionally smooth on [-1, 1] because the derivative goes to infinity as x approaches zero.
