In Exercises 39–44, an equation of a quadratic function is given. a. Determine, without graphing, whether the function has a minimum value or a maximum value. b. Find the minimum or maximum value and determine where it occurs. c. Identify the function's domain and its range. 39. f(x) = 3x – 12x – 1 41. f(x) = -4x² + &r – 3 43. f(x) = 5x? - 5x 40. f(x) = 2x? – &r – 3 42. f(x) = -2r² – 12x + 3 44. f(x) = 6x - 6x %3D %3D %3D
