Question

What is the domain and range ?

Answer 1

Answer:

Domain: [1,∞), {x|x≥1}

Range: (−∞,∞), {y|y∈ℝ}

Step-by-step 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|x≥1}

Range: (−∞,∞), {y|y∈ℝ}

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.
