Which is not true about exponential equation?

[JSmith]

Which of the following is NOT true regarding exponential functions of the form f(x) = ab^x?

a) b represents the growth or decay rate b) a is the initial amount c) f(x) is the final amount or number d) x is the number of growth of decay periods These all seem true to me?

Never mind, I see what it is now. Sorry folks.

f'(x) = a*b^x * ln(b)

So growth rate is a function of 'b' - but by itself 'b' does not represent growth rate.
