The table of values represents a polynomial function f(x).

How much greater is the average rate of change over the interval [7, 9] than the interval [4, 6] ?

**1500**

**1/1500**

**5382**

**1/5382**

Consider the two functions:

g(x)=20(1.5)^{x}

and

f(x) in the table:

**g(0) < f(0)**

**g(0) > f(0)**

**g(0) = f(0)**

**g(0) and f(0) cannot be compared.**
