A function f(x) is defined piecewise for all real numbers x as follows: f(x) = -x + 3 when x ≥ 0, and f(x) = x + 3 when x < 0.
What is the relationship between f(-x) and f(x) for any real number x?
- f(-x) = f(x) for all real x.
- f(-x) = -f(x) for all real x.
- f(-x) = f(x) - 6 for all real x.
- f(-x) = -x - 3 for all real x.
- f(-x) = 0 for all real x.
