Answer:

Hi, The.

The domain of a function is the set of all possible values for x. The range is all possible values for y.

You should be able to see these pretty easily from the graph. If I understand your function correctly:

f(x) = square root(x+2) - 3

then x cannot be less than -2. Your domain is x > -2. In interval notation [-2,โˆž)

The lowest value for y is -3 so the range is y > -3. In interval notation [-3,โˆž)

Hope this helps!
