Question

Examine the following functions for continuity. 

f (x) = x – 5

 

Solution

The given function is f (x) = x – 5

It is evident that f is defined at every real number k and its value at k is k − 5.

Hence, f is continuous at every real number and therefore, it is a continuous function.

  Is there an error in this question or solution?
