The following table shows the amount of air leaking from an inflatable as a function of time:


Time (in minutes)
x Air (in ounces)
f(x)
0 64
1 56
2 48
3 40
4 32


Find and interpret the meaning of the x-intercept in this scenario.
(8, 0); the time it takes all the air to leave the inflatable
(64, 0); the time it takes all the air to leave the inflatable
(64, 0); the time it takes to fill up inflatable with air
