Explain how you can tell the difference between exponential growth and exponential decay by looking at a function rule

See explanation below

Step-by-step explanation:

Exponential growth (decay) is a way of describing the growth (decay) of a certain variable x (money, population, mass, etc..) with respect to time.

It happens when the speed of growth (decay) is proportional to the quantity itself at  any given instant t.

If x(t) is the amount of the variable x at a certain instant t, the exponential growth (decay) can be modeled with the equation

where C is the initial amount of x (when t=0) and its always considered positive, and b, r are constants that depends on the speed of growth (decay).

To find out if x(t) represents an exponential growth, check b and r.

If b > 1 AND r > 0 then x(t) represents an exponential growth. For example,

both represent exponential growth.

If r < 0 AND b >1  OR r > 0 AND 0 < b < 1 then it is an exponential decay. For example,

both represent exponential decay.

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.
