Answer 1

Answer:

  f(x) = 2(1/3)^x

Step-by-step explanation:

To find the parameters of this exponential equation, follow the instructions given in the hint.

__

  b = 6/18 = 1/3 . . . . . divide 6 by 18 to find 'b'

  18 = a(1/3)^-2 . . . . . substitute a point and 'b' in the equation

  18(1/3)^2 = a = 2 . . . . multiply by (1/3)^2

The equation is ...

  f(x) = ab^x

  f(x) = 2(1/3)^x
