Which of the following functions results in a graph that shows exponential decay? f(x) = 4(0.8)x f(x) = 0.7(1.2)x f(x) = 12(3)x f(x) = 0.5(2)x

Respuesta :

The function will show exponential decay if one of the following is true

  • the base is less than 1 and the exponent is positive
  • the base is greater than 1 and the exponent is negative

The function that meets the requirement for exponential decay is ...

[tex]f(x)=4\cdot 0.8^{x}\quad\text{matches the first choice}[/tex]
