Final answer:
The question requires determining the values for which a function is defined. By considering similar examples, for a constant function over a range, the function has a value everywhere in that range.
Step-by-step explanation:
The question asks to determine for what numbers the given function f(x) is defined, based on a piecewise description. The function is not completely specified, but we can address similar examples provided. For instance, if f(x) = 7 for 0 ≤ x ≤ 8, the graph would be a horizontal line at y = 7 between x = 0 and x = 8. Similarly, if the continuous function f(x) is equal to a constant (like 12) and is restricted to a certain range, such as 0 ≤ x ≤ 12, then the probability P(0 < x < 12) is 1 since it covers the entire range of x where f(x) is defined.
