What's the inverse function of y = -3? Is it x = -3??

OpenStudy (anonymous):

It does not have an inverse function.

OpenStudy (firejay5):

Can you explain?

OpenStudy (anonymous):

A function can't map a single input to multiple outputs.

OpenStudy (anonymous):

y doesn't depend on x (or any variable), so you can't express x in terms of y. Hence there is no inverse.
