Question

For this function, which statement is true?

Answer 1

I have no idea how to do this I just need some help

Answer 2

In order for a function to have an inverse, its graph must pass which line test: Horizontal or Vertical?

Answer 3

Vertical?

Answer 4

I asked that knowing you would guess.

Answer 5

like I said I have no idea how to do this

Answer 6

To determine if a function has an inverse, you perform the horizontal line test. Plot the points on an xy plane first. What are the points that represent the function?

Answer 7

Oh did someone give you the answer?

Answer 8

no I just figured it would be this

Answer 9

watch here is another one

Answer 10

Yeah, I don't believe that at all.

Answer 11

If you don't need any help, then why are you posting this?

Answer 12

You said you had no idea how to do it? And now you know how to do it?

Answer 13

because I needed help on the first one! and I did a educated guess

Answer 14

So if you learned, then prove it. Explain how to determine whether a function has an inverse.

Answer 15

like in the last problem I just showed you it is Because f(1) = f(3)=6,f is not one-to -one and f^-1 would have to map a domain value to more than one element in the range so f^-1 does not exist

Answer 16

Very good.

Answer 17

thanks
