Answer:
Given in order:
- 22% growth
- 12% growth
- 12% decay
- 20% decay
Step-by-step explanation:
The exponential function is in the form 
If r is positive (the number in the bracket is larger than 1), then it is <em>exponential growth</em> and if r is negative (the number in the bracket is less than 1), then it is <em>exponential decay.</em>

<u>Growth or Decay by how much???</u>
The amount that is greater than/less than 1
- The first function's number inside the bracket is greater than 1 by 0.22 (22%). So it is "22% growth".
- The second function's number inside the bracket is greater than 1 by 0.12 (12%). So it is "12% growth".
- The third function's number inside the bracket is less than 1 by 0.12 (12%). So it is "12% decay".
- The fourth function's number inside the bracket is less than 1 by 0.2 (20%). So it is "20% decay".
Answer:
By 10° celcius rhe temperature drop that day
Step-by-step explanation:
As in this we will subtract...
9°-(-1°)
= 10°
A.) 4^2
B.) 5^4
C.) 3^1 x 7^4
D.) 2^2 x 9^4
Hope this helps you!!!!!!
C) Quick way:
3x^2+6x+6=0 ---> x^2+2x+2=0,
sum of solutions is the 'x' coefficient multiplied by -1: (-1+i)+(-1-i)=-2-->2
Product is the independent term: (-1+i)(=1+i) = (-1)^2-i^2 = 1+1=2
Takes longer to write it down!
