The distance between two cities is 400 miles. The function represents the average speed a person must travel over x hours to cover the distance. Which best compares the mathematical domain and range with the reasonable domain and range? mathematical: {x ∈ R} {y ∈ R} reasonable: x > 0, y ≥ 0 mathematical: {x ∈ R ∣ x ≠ 0} {y ∈ R ∣ y ≠ 0} reasonable: x > 0, y > 0 mathematical: {x ∈ R} {y ∈ R} reasonable: x ≥ 0, y ≥ 0 mathematical: {x ∈ R ∣ x ≠ 0} {y ∈ R ∣ y ≠ 0} reasonable: x ≥ 0, y ≥ 0
