Question

Please help me, I'm really bad at this stuff! I will give you a medal!

Answer 1

The depth d(x), in feet, of a circular swimming pool at a point x feet from the edge is represented by the function below.



If the depth varies from 1 foot to 4 feet, which inequality describes the domain of the function?

A) 0 ≤ x ≤ 8

B) 0 ≤ x ≤ 24

C) 0 ≤ x ≤ 40

D) 1 ≤ x ≤ 8

Answer 2

\[1=1+{\dfrac{x}{8}}\]and \[4=1+\dfrac{x}{8}\]

Answer 3

Okay??

Answer 4

So is it B?

Answer 5

Oops wrong letter!

Answer 6

Well, solve for x in both those... you get? 0 and 24... that's your domain.
So yes, B

Answer 7

Wait I was right?

Answer 8

That's weird, because I'm usually wrong!

Answer 9

haha, well you got it right.
