9.2 Exponential Decay

SOLVED:In an exponential decay function, the base of the exponent is a value between 0 and 1 . Thus, for some number b>1 the exponential decay function can be written as f(x)=a ·((1)/(b))^x . Use this formula, along with the fact that b=e^n, to show that an exponential decay function takes the form f(x)=a(e)^-n x for some positive number n
