 Use the given formula:

(i) A function f(x) is said to be continuous at a point x = a of its domain, if

\lim _{x \rightarrow a^{+}} f(a+h)=\lim _{x \rightarrow a^{-}} f(a-h)=f(a)

Given:

 f(x)=|x|+|x-1|

Solution:

Both are polynomial function and we know that the polynomial functions are continuous everywhere,
