You are correct in stating you have a decay. This is because the base of the exponential 0.82 is in the form 1+r where 1+r = 0.82 solves to r = -0.18
The negative r value means we have decay.
The rate of decay is 18% since 0.18 = 18/100 = 18%
For example, if we started with 100 items then after 1 unit in time, you'd have 82 items since 100-18 = 82
1.) 24% 24/100 0.24
2.) 7% 7/100 0.07
3.) 36% 36/100 (9/25) 0.36
4.) 20% 20/100 (1/5) 0.20
5.) 15% 15/100 (3/20) 0.15
Step-by-step explanation:
f(x) = 4x - 7
f(2) = 4(2) - 7
f(2) = 8 - 7 => 1
