The given function y = 3x^2 - 3x + 4 is a quadratic function.
The leading coefficient is positive, so the parabola plot is open upward.
The domain of the function is the set of all real numbers. ANSWER
The range is the set of all real numbers from the minimum value (the vertex y-value) to infinity.
The minimum value of this quadratic function is at x = = = .
The minimum y-value is = 3.25.
So the range of the function is [3.25,oo). ANSWER
Solved. // All questions are answered.
