which function represents exponential decay?
a)y=14(0.95)^x
b)y=14(1.95)^x
c)y=14x^1.95
d)y=14/0.95
​

Respuesta :

Answer:

a

Step-by-step explanation:

We are looking for an exponential function [tex]y=a(r)^x[/tex] where r is less than 1.

a works because it is in the form [tex]y=a(r)^x[/tex] where r is less than 1.

b is in the form [tex]y=a(r)^x[/tex] but r is more than 1.

c. and d. are not even exponential functions.

c. is a polynomial

d. is a constant polynomial (no variable)
