Answer:
You can restrict the inverse function y = |x| to make it a one-to-one function by restricting the domain to either positive or negative values. This can be done by setting a condition on the x-values that are allowed.
For example, if we want to restrict the domain to positive values, we can define the function as:
f(x) = |x|, for x >= 0
This will make the inverse function one-to-one, since each positive x-value will now only correspond to one unique y-value (i.e. the absolute value of x).
