A square root function has a domain of x ≥ –4 and range of y ≥ 2 . Which of the equations below match this description?

y = root(x - 4) +2
Image with alt text: y = root(x - 4) +2

y = root(x + 4) + 4
Image with alt text: y = root(x + 4) + 4

y = root(x - 2) - 4
Image with alt text: y = root(x - 2) - 4

y = root(x + 2) - 4

1 answer

The correct equation that matches the given domain and range is:

y = root(x + 2) - 4
