The function $f(8) = |8|$ represents the absolute value of 8.

The absolute value of a number is the distance of that number from zero on the number line, regardless of the direction. In this case:

$|8| = 8$

Therefore, $f(8) = 8$.

Would you like more details or further explanations on absolute values?

Here are five related questions for further exploration:

1. What is $f(-8)$ if $f(x) = |x|$?
2. How does the absolute value function behave for negative numbers?
3. What is the derivative of the absolute value function, $f(x) = |x|$, for $x = 8$?
4. How can we use the absolute value function to describe distances on the number line?
5. What is the absolute value of $|0|$ and why?

Tip: Absolute values always return a non-negative result, regardless of whether the input is positive or negative.
