#

then it's (-inf, 1) u [2, inf)

#

no, how come?

#

yes, but that doesn't have anything to do with the range

#

Let's see

#

That's true

#

So Im(f) = (-inf,inf)

#

Why (-inf,1)?

#

It has to be like (-inf,2] U (1,inf)

#

No need for that, a graph is much better

#

Tbh I've never made such a table

#

So you can show me solved examples

#

Yes

#

Ok so you just need to replace that one -inf to inf in your answer

#

Cuz it's coming down from inf to 1

#

It's not going up

#

Yes I'm talking about yours
