The table below represents the volume of a liquid sample as a function of its temperature:

temperature (°c)
x

volume
(ml)
f (x)

11

95

16

100

21

105

26

110

the average rate of change of f(x) between x = 11 to x = 21 is per °c and represents the rate of change of volume per degree rise in temperature.
