Final answer:
f(12) represents the value of the function f at the input of 12.
Step-by-step explanation:
Based on the given information, f(12) represents the value of the function f at the input of 12.
Since the function is defined as f(x) = 12 and restricted to the interval 0 ≤ x ≤ 12, we can conclude that any input within this interval will yield the output of 12.
Therefore, f(12) is equal to 12 in this context.
