Find the maximum and minimum values of f , if any, of the function given by `f(x)=|x|,x in R`.

Explanation

To find the maximum and minimum values of the function \( f(x) = |x| \) for \( x \in \mathbb{R} \), we can follow these steps:

### Step 1: Understanding the Function
The function \( f(x) = |x| \) represents the absolute value of \( x \). This means that:
- For \( x \geq 0 \), \( f(x) = x \)
- For \( x < 0 \), \( f(x) = -x \)
