Question

A function is shown below:

Answer 1

Last one:

f(x)= (1+r)^x, then find r=0.07-1=-0.93,

negative---> decay, and then 0.93==93%

Answer 2

Answer:

Exponential decay of 93%

Step-by-step explanation:

A function is shown below:

f(x) = (0.07)^x

Exponential formula is

$f(x)= a(1+r)^t$

r is the rate of growth or decay

From the given f(x) , we have 1+r = 0.07

Subtract 1 from both sides

$r= 0.07 -1$

$r= -0.93$

To get % we multiply by 100

r= -93%

the value of 'r' is negative , so its exponential decay

Exponential decay of 93%
