Exponential Growth and Decay Supposey=ekx. Thendy/dx=kekx. Sincey=ekx,dy/dx=ky. This is an example of adifferential equation. Ify=2ekx, thendy/dx=2kekx, which is once again equal toky. More generally, ify=Aekx, thendy/dx=Akekx, which is once again equal toky. So ...

Exponential Growth and Decay Recall that if y=f(t)( then f)(t)=dyt is called the rate of change of y with respect to t. Another very important measure of rate of change is the relative rate of change f,(t) y, = .f(t) y. ...
Growth and DecayBut sometimes things can grow (or the opposite: decay) exponentially, at least for a while.So we have a generally useful formula:y(t) = a × ekt Where y(t) = value at time "t" a = value at the start k = rate of growth (when >0) or decay (when <0) t =...
What is the difference between linear and exponential? Exponential Functions. In linear functions, rate of change is constant: asx goes up, y will go up a consistent amount. In exponential functions, the rate of change increases by a consistent multiplier—it will never be the same, but there...
