# 5 d) Examine the following functions for continuity.

Given function is

for x > 5  , f(x) =  x - 5
for x < 5 , f(x) = 5 - x
SO, different cases are their
case(i)   x > 5
for every real number k > 5   , f(x) = x - 5 is defined

Hence, function  f(x) = x - 5 is continous for x > 5

case (ii)      x < 5
for every real number k < 5   , f(x) = 5 - x is defined

Hence, function  f(x) = 5 - x is continous for x < 5

case(iii)    x = 5
for x  = 5   , f(x) = x - 5 is defined

Hence, function  f(x) = x - 5 is continous for x = 5

Hence, the function  is continuous for each and every real number
