Answer:
The function f is continuous everywhere because the three conditions for continuity are satisfied for all values of x.
Step-by-step explanation:
The definition of continuity of a function is:
A function f (x) is continuous at x = a if the following three conditions are met:
- f(a) exists
- [tex]\lim_{x \to a} f(x)[/tex] exists
- [tex]\lim_{x \to a} f(x)[/tex] = f(a)
We check each condition when x=1
1) f(x)=|x-1| so f(1)=|1-1|=0
The value of f(x) exits when x=1
2) The limit as x approaches 1 of |x-1| can be checked with lateral limits:
[tex]\lim_{x \to 1^{-}} |x-1|[/tex]=0
[tex]\lim_{x \to 1^{+}}|x-1|[/tex]=0
Both limits have the same value to the limit exist when x approaches 1.
3) [tex]\lim_{x \to 1} |x-1|[/tex]=0=f(1)
The limit as x approaches 1 of f(x) is equal to the value of f(x) exits when x=1

The function f is continuous everywhere because the three conditions for continuity are satisfied for all values of x.
Given that,
Function f(x) = | x-1 |
The function f is discontinuous at x = 1 because f is not defined at x = 1.
The function f is discontinuous at x = 1 because limx→1 f(x) does not exist.
The function f is discontinuous at x = 1 because limx→1 f(x) exists, but this limit is not equal to f(1).
We have to find,
The function f is continuous everywhere because the three conditions for continuity are satisfied for all values of x.
According to the question,
The definition of continuity of a function is:
A function f (x) is continuous at x = a if the following three conditions are met:
- f(a) exists
- [tex]lim_x_-_a = f(x)[/tex] exists
- [tex]lim_x_-_a = f(a)[/tex]
We check each condition when x = 1
- f(x) = x-1| so f(1) = |1-1| = 0
The value of f(x) exits when x=1
- The limit as x approaches 1 of |x-1| can be checked with lateral limits:
[tex]= lim_x_-_1- = |x-1| = 0\\= lim_x_-_1+ = |x-1| = 0[/tex]
Both limits have the same value to the limit exist when x approaches 1.
- The function f is discontinuous at x = 1 because limx → 1 f(x) exists, but this limit is not equal to f(1).
[tex]= lim_x_-_1 = |x-1|[/tex] = 0 = f(1)
The limit as x approaches 1 of f(x) is equal to the value of f(x) exits when x=1.
Hence, The function f is continuous everywhere because the three conditions for continuity are satisfied for all values of x.
