Answer 3

@Vocaloid

Answer 4

i can help

Answer 5

I need someone legit tho, r u good at math?

Answer 6

@Ferredoxin4

Answer 7

I’m stuck

Using limits would be easier, if you are aware of that

Answer 9

Also once again i suggest you memorize end behaviors of parent functions and their transformations well, then you can eye the D&R without work

Answer 10

Can you link me the pictures of parent functions pal? Will appreciate your work.

Answer 11

Or use a graphing calculator

Answer 12

I can’t use limits here...it’s literally the bigining of the book.

Answer 13

That’s ok, i’ll Find it myself. But tell me do i need to find the domain of the inverse of the original function to find range?

Answer 14

K i’m Going to draw the solution and you check.

Answer 15

What do i do next?

Answer 16

Did I do something wrong?

Answer 17

Tbh I've rarely used inverse but do you know how to find critical points?

The domain of the original is the range of the inverse, so find it's domain by plugging it in

Answer 18

Then use it's critical points and plug it in

Answer 19

I'll let @Gdeinward or @Hero or @dude take over. I have to go
