Which kind of function best models the data in the table? Use differences or ratios.
x y
0 1.7
1 6.8
2 27.2
3 108.8
4 435.2
The data seems to be multiplying by a constant factor each time.
Using ratios:
1.7 * 4 = 6.8
6.8 * 4 = 27.2
27.2 * 4 = 108.8
108.8 * 4 = 435.2
Therefore, the function that best models the data in the table is an exponential function of the form y = 1.7 * 4^x.
