13. Is the function defined by
a continuous function?
Given function is
given function is defined for every real number k
There are different cases for the given function
case(i) k > 1
Hence, given function is continuous for each value of k > 1
case(ii) k < 1
Hence, given function is continuous for each value of k < 1
case(iii) x = 1
Hence, x = 1 is the point of discontinuity
