Which table represents exponential growth?

Answer

Table with 2 columns and 5 rows.Row 1: Column 1, 'x'; Column 2, 'y' Row 2: Column 1, '1'; Column 2, '2' Row 3: Column 1, '2'; Column 2, '4' Row 4: Column 1, '3'; Column 2, '6' Row 5: Column 1, '4'; Column 2, '8'

Explanation

Exponential growth has a constant multiplicative factor: each time x increases by 1, y is multiplied by the same number. In choice C, the y-values 2, 4, 8, and 16 double each time, so this table represents exponential growth. The other tables do not have a constant ratio between consecutive y-values.
