The distance d, in miles, a small plane is from its final destination is given by d(t)=250-100t, where t is the time, in hours, remaining for the flight. Find and discuss the meaning of the intercepts of the graph of the function.
let t = 0 , d(0) = 250 - 0 = 240
At the beginning the plane is 250 miles from its destination , point (0,240)
let d(t) = 0
0 = 250-100t
100t=250
t = 2.5
after 2.5 hrs, the plane has reached its destination
point (2.5, 0)
