Answer:
exponential
Explanation:
type of function that describes the amplitude of damped oscillatory motion is exponential because as we know that here function is
y = A × [tex]e^{\frac{-bt}{2m}}[/tex] × cos(ωt + ∅ ) ..................................... ( 1 )
here function A × [tex]e^{\frac{-bt}{2m}}[/tex] is amplitude
as per equation ( 1 )it is exponential
so that we can say that amplitude of damped oscillatory motion is exponential
