Question

Please help me ASAP!!!

Answer 1

The initial function is:

`y=\sqrt[]{x-3}-9`

So the domain will be all values that made the root positive so:

`\begin{gathered} x-3=0 \\ x=3 \end{gathered}`

So the domain will be:

`\text{domain}\to\mleft\lbrack3,\infty\mright)`

So are all the numbers greater than or equal to 3
