The graph of the revenue function f(x) = –0.07x2 + 3.5x is used to determine revenue in hundreds of thousands of dollars, where revenue depends on the number of thousands of items sold, x. How do the mathematical domain and reasonable domain compare? mathematical: –∞ < x < ∞ reasonable: 0 ≤ x ≤ 25 mathematical: –∞ < x < ∞ reasonable: 0 ≤ x ≤ 50 mathematical: 0 < x < ∞ reasonable: 0 ≤ x ≤ 25 mathematical: 0 < x < ∞ reasonable: 0 ≤ x ≤ 50
