Given the points a (- 1, m), B (- 2, n) on the image of quadratic function y = - x?, the size of M and N are compared
First read and then know the points a (- 1, m), B (- 2, n) on the image of quadratic function y = - x, compare the size of M and n
When x < 0, the function value y of y = - x increases with the increase of X, while - 1 > - 2, so m > n
Use the above information to answer the following questions:
Given that point a (a + 1, m) and point B (- 1, n) are on the image of quadratic function y = x, try to compare the size of M and n
