Does each function describe exponential growth or decay? drag and drop the equations into the boxes to correctly complete the table. 20 points

Growth: Equation 2

Decay: Equation 1,3,4,5

Step-by-step explanation:

Anything that has a total value of below 1 before the power experiences exponential decay, as you are decreasing.

For the first one:

y = 100(0.5) , this is experiencing decay as multiplying the 0.5 by an increasing power will decrease the amount the 100 is multiplied with.

Second one:

y = 0.1(1.25) , this is displaying exponential growth because the value inside the brackets is higher than one, and whatever number this is multiplied with in the power it will increase.

Third one:

y = ((0.097)) , is showing exponential decay because the amount inside the brackets (0.97) is constantly being multiplied with the 0.5 power, which decreases the number below one.

Fourth one:

This is showing decay because the number inside the brackets is lower than one.

Fifth one:

This is also showing decay because the number inside the brackets are lower than 1.

Growth function = 2nd

Decay function = 1st, 3rd, 4th, 5th

Step-by-step explanation:

The general exponential function is

where, a is the initial value and b is growth or decay factor.

If 0<b<1, then it is a decay function and if b>1, then it is a growth function.

In function 1,

It can be rewritten as

Since b=0.5<1, therefore it is a decay function.

Similarly,

In function 2,

b=1.25>1, therefore it is a growth function.

In function 3,

b=0.97<1, therefore it is a decay function.

In function 4,

b=0.98<1, therefore it is a decay function.

In function 5,

b=0.5<1, therefore it is a decay function.

Therefore, only 2nd function is growth function and all other functions are decay function.
