Which function must have a restricted domain in order to have an inverse function?
a. f(x)= 6x -10
b. f(x) =8x^2-6x+10
c. f(x) =3(x-2)^3+1
d. f(x)= √x+3

B

Step-by-step explanation:

Consider the function

Rewrite it as

The domain of this function is and the range is

Find the inverse function:

So, the domain of the inverse function is and the range will be

So, the domain must be restricted

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
