The function 5/x^2 is not a one-to-one function. A one-to-one function is a function where each element of the range is paired with exactly one element of the domain.
In the function 5/x^2, for example, if we have x = 2 and x = -2, the values of the function would be the same since (-2)^2 = 2^2 = 4, and 5/4 is the same as 5/(-4) = -5/4. This means that different inputs can yield the same output, violating the one-to-one requirement. Therefore, 5/x^2 is not a one-to-one function.
Is 5/ x^2 a one- to - one function. How?
