Final answer:
The question's equation appears to have a typo and lacks a variable. Assuming an intended linear function, the inverse will be a function with a restricted domain. However, a correct equation is needed to specify this domain.
Step-by-step explanation:
The original question seems to have a typo, as the expression y = 22 + 3 does not contain a variable to define its domain. Assuming the question meant to include a variable such as x (e.g., y = 22 + 3x), we could discuss the domain for which its inverse is also a function. Since linear functions have inverses that are functions when they are one-to-one, this linear equation would need a restricted domain to be one-to-one. Therefore, any of the options that restrict the domain to a certain range can make the inverse a function. However, more context or a correct equation is necessary to provide an accurate domain.
