Researchers in Antarctica discovered a warm sea current under a glacier that is
causing the glacier to melt. The ice shelf of the glacier had a thickness of
approximately 450 m when it was first discovered. The thickness of the ice shelf is
decreasing at an average rate of 0.06 m per day.
Which function can be used to find the thickness of the ice shelf in meters x days
since the discovery?
A) t(x) = 450 - 0.06x
B) t(x) = -0.06(x – 450)
C) t(x) = -0.06(x – 7500)
D) t(x) = 450 + 0.06x
E) t(x) = -0.06(x + 450)
F) t(x) = -0.06(x + 7500)
