SOLUTION: A submarine that is 7500 meters below sea level surfaces at a rate of 80 meters per minute. The depth of the submarine after M minutes is given by d(m) = -7500 + 80m Give the range

Question 736049: A submarine that is 7500 meters below sea level surfaces at a rate of 80 meters per minute. The depth of the submarine after M minutes is given by d(m) = -7500 + 80m Give the range and domain of this function make a table for this function
and graph

The depth of the submarine after M minutes is given by
The limitations here are that starts out at m and
rises, but , since it's a submarine, it can't go any higher than . That
would put it above the water's surface.
----------------
Also the equation is set up for . Since the minutes can't
be less that , is the lowest depth that the equation can habndle
-----------------
Now I can chart these 2 positions, , and
(1)
meters

minutes
------------
(2)
meters

minutes
-----------------
So, the range is to meters
The domain is to minutes
--------------------------------------
Here's the plot:
