WebTo answer you question of if it is always true, the answer is no. If you start from the quadratic parent function, y=x^2, then y cannot be negative. One way to include negatives is to reflect it across the x axis by adding a negative y = -x^2. With this y cannot be positive and the range is y≤0. WebMay 9, 2024 · Using the quadratic formula and taking the average of both roots, the x -coordinate of the stationary point of any quadratic function a x 2 + b x + c (where a ≠ 0) is given by x = − b 2 a. When x = − b 2 a, y = c − b 2 4 a. Therefore the maximum or minimum value of the quadratic is c − b 2 4 a.
