The exponential function represented by this table can be written in the form y = ab^x, where a is the initial value and b is the growth factor.
Looking at the table, we can see that the initial value (when x = 0) is 33, so a = 33.
To find the growth factor, we can look at the ratio of consecutive y-values:
66/33 = 2 (the growth factor here is 2)
1212/66 = 2 (the growth factor here is also 2)
2424/1212 = 2 (the growth factor here is also 2)
Since the growth factor is consistent for all pairs of consecutive y-values, we can conclude that b = 2.
Therefore, the equation of the exponential function represented by this table is y = 33 * 2^x.
