No, things that grow exponentially grow at a rate proportional to its size.
Furthermore, that's not an exponential curve, genius.
At least not yet.
1. Yes it is an exponential curve.
2. And it has a constant growth rate.
An exponential growth is characterized by the following equation:
k - is the constant rate of growth.
So in the graphs in the post above, say the money supply is growing at a constant rate of 4%, it will look exactly like those curves. And BTW, what means it is growing at a rate proportional to it size, and that rate is constant.
