Question

Given the exponential function A (x)= P(1+r)^2 what value will or make the function of decay function

Answer 1

Answer:

r<0

Step-by-step explanation:

The exponential function $A(x)= P(1+r)^2$ is

• a decay function, if $1+r<1;$
• an increase function, if $1+r>1.$

Thus, for the exponential function to be the exponential decay function the following must hold

$1+r<1\Rightarrow r<0.$
