The table below shows the functions to represent the sale f(t), in thousands, of four companies in t years:

company a b c d
sale f(t) = 1.05t f(t) = 0.75t f(t) = 1.212t f(t) = 0.9712t

which of the following companies showed an exponential decay in sale? (1 point)

company a and company c

company b and company d

company c and company d

company a and company b

Company B and Company D shows exponential decay in sale

Step-by-step explanation:

Company    A                      B                   C           D

Sale

General form of exponential function is given by

Where 'a' represents the initial value

b represents the exponential growth or decay

If b > 1 then it is an exponential growth

If 0<b<1 then it is an exponential decay

b values is 1.05 that is greater than 1 so it is exponential growth

b values is 0.75 that is less than 1 so it is exponential decay

b values is 1.212 that is greater than 1 so it is exponential growth

b values is 0.9712 that is less than 1 so it is exponential decay

Company B and Company D shows exponential decay in sale

answer: 177/8
