Answer 1

Given :  Tables with 4 Data Entries

To find : Which table shows exponential decay

Solution:

y = abˣ  where b < 1   shows   exponential decay

x       y

1        16

2       8

3       4

4       2

y  = 32 (1/2)ˣ

Hence above table Shows exponential decay

x       y

1        16

2       12

3       8

4       4

y = 20 - 4x    ( Linear)
