Answer:
Step-by-step explanation:
The depth function is:
After 3 minutes, a submarine had descended to −320 feet.
This means that 
. So
After 8 minutes, the submarine had descended to −420 feet.
This means that 
. So
From the first equation:
So
And
So
The mode is the number repeated most often, so if we arrange these numbers in order, we can see what numbers repeat the most-
1 1 1 2 3 3 5 7 8 8 9
The number that repeats the most is 1
(1 counted 3 times)
(3 counted twice)
(8 counted twice)
F(x) = -2(x + 3)^2 - 1
vertex = (-3, -1)
domain is all real number values of x and
range is all real numbers values of y less than or equal to -1.
