Ineed to know 3b. it ask to find the inverse of numliters and call it temp

To find the inverse "relation" of any equation, simply do a switcharoo on the variables, now, if the resulting inverse "relation" happens to be a function, as the "vertical line test" has it, then is also an "inverse function" and as 3a said it, yes, only one-to-one functions have inverse functions

so let's see Numliters(t) then



now, name wise, heck, you can call it whatever you want, even spaghetti



anyhow...that's the inverse function

Ibelieve the answer is b
