In math what is the meaning of |x|x|x|x|

f (x) = |x| is the absolute value function.

Step-by-step explanation:

The given expression |x| is the symbol for modulus function.

Hence, f (x) = |x| is a modulus function of x.

This is also known as the absolute value function of x.

It is defined as If f (x) = |x|, then

f (x) = x for x ≥ 0 and

f (x) = - x for x < 0.

Therefore, if x = 5 then it is ≥ 0 and by definition f (x) = x = 5

and if x = - 5, then it is < 0 and by definition f (x) = - x = - ( - 5) = 5

So, therefore, the absolute value function always give the positive value of a number or expression. (Answer)
