Answer:

• 20% decay
• 40% growth
• 80% decay
• 40% decay
• 60% growth

Step-by-step explanation:

The "growth factor" is the number that has an exponent. Subtracting 1 from that gives the growth rate. The growth rate can be expressed as a percentage by multiplying it by 100%. If it is negative, it represents a rate of decay.

For example, the growth factor of 0.8 is a growth rate of 0.8-1 = -0.2 = -20%, a decay of 20%.

Here, we'll list the growth factor and the rate of change:

  growth factor ⇒ rate of change

  0.8 ⇒ 20% decay

  1.4 ⇒ 40% growth

  0.2 ⇒ 80% decay

  0.6 ⇒ 40% decay

  1.6 ⇒ 60% growth
