Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
y=9300(0.991) ^6


Sagot :

Using exponential function concepts, it is found that it represents a decay of 0.9%.

What is an exponential function?

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem, the function is:

[tex]A(t) = 9300(0.991)^{6t}[/tex]

Hence:

[tex]1 - r = 0.991[/tex]

[tex]r = 0.009[/tex]

Thus, it represents a decay of 0.9%.
