The general formula for exponential growth and decays is:

if k>0 then then it is an exponential growth function. If k<0 then the function represents an exponential decay.
Now we need to classify each of the functions:
1.
The function

can be wrtten as:

comparing with the general formula we notice that k=2, therefore this is an exponential growth.
2.
The function

can be written as:

comparing with the general formula we notice that k=-4, therefore this is an exponential decay.
3.
The function

comparing with the general formula we notice that k=-1, therefore this is an exponential decay.
Answer:
31.3 feet
Step-by-step explanation:
-23.6+13.4 = -10.2
-10.2 - 21.1 = -31.3
Step-by-step explanation:
what is THE partial product ? there is a mistake in your problem description.
it must read "what are valid partial products".
1262×3 has the following partial products :
1000×3 = 3000
200×3 = 600
60 × 3 = 180
2×3 = 6
-----------
3786
so, D seems to be the best answer, because both numbers are partial products here.
A, B and C have each only one correct.
Answer: x = − 10
Step-by-step explanation:
X − 8 = − 20 =
12 − 28 = − 16
28 = − 16
2 − 12 = − 10
x = − 10
Answer:
Recall that the height of the object, in meters, is a function of elapsed time, in seconds. Thus what
means is that the object is at a height of 8 meters when 12 seconds have passed since its launch.
