Given the points a (- 1, m), B (- 2, n) on the image of quadratic function y = -- X ^, compare the size of M and n

Y= -x^^2
The symmetry axis of quadratic function is x = 0, that is Y axis
The opening is downward and the point farther away from the axis of symmetry is lower
B is far from the axis of symmetry
So m > n
