Recall that
So we have
So either .
Since , we expect , so we take the negative square root. Then
This then means we have
Domain = all possible x values
You can see it starts from -5 and it goes till 4. Therefore domain -5 < x < 4
Solution: [-5,4]
c=PI*d
divide both sides by PI to get d by itself
d = c/PI
Answer:
