Math Problem Statement

Use the following function rule to find f(3).

f(x) = 3 |–8 − x|

f(3) =

Solution

The value of f(3)f(3) is 3333.

Would you like further details or have any questions? Here are five related questions to extend your understanding:

  1. What is the significance of the absolute value in this function?
  2. How would you calculate f(3)f(-3) for the same function?
  3. How does the function behave as xx increases or decreases?
  4. What happens to f(x)f(x) if the absolute value were removed?
  5. Can you rewrite the function without the absolute value for x>8x > -8?

Tip: The absolute value function, x|x|, always returns a non-negative value regardless of the sign of xx.
