WebExplanation: Let's take an example of quadratic equation f (x) = 3x 2 + 4x + 7. Since the double derivative of the function is greater than zero, we will have minima at x = -2/3, and the parabola is upwards. Similarly, if the coefficient of x 2 is less than zero, then the function would have maxima. Hence, by using differentiation, we can find ... hyphens in measurementsWebTo get the minimum value there are two options: 1) By looking at the equation after we have completed the square we can see that we will always have the $+5$ term, so we need to minimize the $2(x-1)^2$ term. hyphens can be used to form compound wordsWebIn many quadratic max/min problems, you'll be given the formula you need to use.
