Question

Plz help do tonight AT 3

Answer 1

I think its the first one

Explanation:

you first subtract 2

the next one you subtract 1

then 0

then - 1

Answer 2

`y =(4)/(5) x`

Explanation:

From the table, note that for
`x\in(0, \infty)` we have
`x> y`, on the other hand for
`x\in(-\infty, 0)` we have
`x < y`.

Considering the basic case
`x = 0`, we conclude
`y = 0 \iff x = 0`, thus
`y = x- 2` is not an option.

Also, once the domain and range have the same signal,
`$y =-(5)/(4) x$` can't be an option as well.

Finally, taking
`x = 10 \implies y=8`, testing the two remaining cases

`$y =(5)/(4) x \implies y=(5)/(4) \cdot 10 \implies y = 12.5$`

`$y =(4)/(5) x \implies y=(4)/(5) \cdot 10 \implies y=8$`

The function is
`y =(4)/(5) x`
