Question

I really need help!!

Refer to the picture above

Answer 1

1) Domain is
`\{-2,0,2,4\}`

Range is
`\{3,-1,0\}`

2) Domain is
`\{-3,-1,0,3\}`

Range is
`\{-1,0,1,2,3\}`

Explanation:

Domain refers to the set of all
`x` values of a relation.

Range refers to a set of all
`y` values of a relation.

1) For the first relation the domain and range can be found out as following:

The set of
`x` values of the relation given is
`\{-2,0,2,4\}`.

So Domain is
`\{-2,0,2,4\}`

The set of
`y` values of the relation given is
`\{3,-1,0\}`.

So Range is
`\{3,-1,0\}`

2) for the second relation, we need to label the points plotted on graph first in order to get the
`x` and
`y` values.

Points are
`(-3,1), (-1,-1), (0,0), (3,2)\ and\ (3,3)`

The set of
`x` values of the relation given is
`\{-3,-1,0,3,3\}`.

So Domain is
`\{-3,-1,0,3\}`

The set of
`y` values of the relation given is
`\{-1,0,1,2,3\}`.

So Range is
`\{-1,0,1,2,3\}`
