An exponential function is expressed in the form y=axb^x. The relation represents a growth when _______ and a decay when ______.
seropon [69]

Answer:

Growth when: b>1.

Decay when: 0<b<1.

Step-by-step explanation:

Any function in the form f(x)=a{\times}b^x , where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b.

If 0 < b < 1 this is an example of an exponential decay.

The general shape of an exponential with b > 1 is an example of exponential growth.

Hence,

An exponential function is expressed in the form f(x)=a{\times}b^x,   The relation represents a growth when  b >1 and a decay when 0<b<1.

3. The total cost for 9 bracelets, including shipping was $72. The shipping charge was $9. Define your variable and write an equ
ikadub [295]

Answer:

The equation that models the cost of each bracelet is 72=9x+9. Cost of each bracelet is $7.

Step-by-step explanation:

Let the cost of each bracelet is defined by the variable x.

Cost of 9 bracelet is 9x. The shipping cost is $9. Therefore the total cost of 9 bracelets, including shipping is

\text{Total Cost}=9x+9

The total cost for 9 bracelets, including shipping is $72.

72=9x+9

Subtract 9 from both sides

72-9=9x+9-9

63=9x

Divide both sides by 9.

7=x

Therefore the cost of each bracelet without shipping changes is $7.
