### In the exponential growth or decay function, explain the circumstances that cause k to be positive or negative

### Prove that if $$\displaystyle{y}={y}^{{{0}{e}{k}{t}}},$$ where $$\displaystyle{y}_{{{0}}}$$ and k are constants, then $$\displaystyle{\frac{{{\left.{d}{y}\right.}}}{{{\left.{d}{t}\right.}}}}={k}{y}$$ (This says that for exponential growth and decay, the rate of change of the population is proportional to the size of the population, and the constant of proportionality is the growth or decay constant.)
