Question

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.

The function d of x equals 1 plus one-eighth x]

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

0 ≤ x ≤ 8

0 ≤ x ≤ 24

0 ≤ x ≤ 40

1 ≤ x ≤ 8

Answer 1

Answer 2

How ?

Answer 3

Well if oyu plug in 24 for x, you get 1/3 o 24=3+1=4 the outer rane of depths

Answer 4

Ok...then ?

Answer 5

and if oy plug in 0, you get 1/3 of 0=0+1 which is the lower range off depths that you can have

Answer 6

ya got it :)
