Question

A square root function has a domain of x ≥ –4 and range of y ≥ 2 . Which of the equations below match this description? (1 point)

Answer 1

\[y=\sqrt{x-4}+2\]
\[y=\sqrt{x+4}+2\]
\[y+\sqrt{x-2}-4\]
\[y=\sqrt{x+2}-4\]

Answer 2

the domain of this function is given by the domain of the square root.
To get that you need to do an inequality

The argument of the square root must be greater or equal to 0.

Hope this helps

Answer 3

not really

Answer 4

Well lets start with the first one:

\[x-4 \ge 0\]

now do this for all 4 choices and choose the one who matches with the given domain

Answer 5

is it the second one?

Answer 6

yep
