Question 817803
I just need to know how to find the answer and I need is before 3 today. A submarine that is 7500 meter 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 of the function. Show your work
------
The least depth it can have is zero, which is its depth when on the surface.
Solve -7500+60m = 0
60m = 7500
m = 125.
-------
Range = -7500<= y <=0
