Question

What is the domain and range ?

Answer 1

Domain: [1,∞), x≥1

Range: (−∞,∞), y

Explanation:

The equation of that line is
`y^(2)=x-1`, and the domain and range of
`y^(2)=x-1` is:

Domain: [1,∞), x≥1

Range: (−∞,∞), y

Hope this helps! :)

Answer 2

Domain is the set of first numbers of the order pairs.

Range is the set of second numbers of the ordered pairs.
