Given that f [x} = AX-1 {a > 0, a ≠ 1} has both the domain of definition and the range of value [1,2], what is the value of a

Given that f [x} = AX-1 {a > 0, a ≠ 1} has both the domain of definition and the range of value [1,2], what is the value of a

Are you sure there is no problem with this problem? If f (x) is monotonically increasing and the definition field is [1,2], the value field can't be [1,2]
