Find out whether the function has a minimum value or a maximum value without graphing it. Determine the minimum or maximum value and the point where it occurs. Also, find out the domain and range of the function. f(x) = 9x²-54x+83

• A. Maximum value = 3 at x = 2; Domain: (-∞, ∞); Range: (-∞, 3]
• B. Maximum value = 2 at x = 3; Domain: (-∞, ∞); Range: (-∞, 2]
• C. Minimum value = 3 at x = 2; Domain: (-∞, ∞); Range: [3, ∞)
• D. Minimum value = 2 at x = 3; Domain: (-∞, ∞); Range: [2, ∞)

Answer: (D)
