Did you know?
Web1) 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. Because it's square it will never be negative, however, we can make it equal to zero. So, 2 ( x − 1) 2 = 0, therefore ( x − 1) 2 = 0 and x − 1 = 0 so x = 1 is the minimum point. WebSince 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 …
