If the image y = a ^ 2 and the function y = | a ^ X-2 | (a > O, and a is not equal to one) have two common points, then the value range of a is?

If the image y = a ^ 2 and the function y = | a ^ X-2 | (a > O, and a is not equal to one) have two common points, then the value range of a is?

Using image method: when a > 1, we can know a ^ 2
