Given the following equation of an exponential function r = 10.5(0.535) determine the decay rate. a. 0.535% b. 10.5% c. 50% d. 46.5%

Correct choice is D

Step-by-step explanation:

Consider the exponential function

The exponential function of exponential decay can be written as

where r is the decay rate.

Note that 1-0.535=0.465. The decimal 0.465 is 46.5% and this percent represents the rate of exponential decay.

-2

Step-by-step explanation:

Because the x is being multiplied by 2 you would do the same for the y and multiply it by 2 to get -2
