Question

I dentify the domain and range and sketch the graph


`y = sqrt { - x - 3 - 3}`
​

Answer 1

Explanation:

y=√(-x-3) - 3

y exisit : - x -3 ≥ 0

- x ≥ 3

x ≤ - 3 the domain is : D=] -∞,-3 ]

y=√(-x-3) - 3

y + 3 = √(-x-3)

x exisit : y + 3 ≥ 0 ; y ≥ -3

the range is : w = [- 3,+ ∞ [

look the graph
