Write an equation or function that models the number of bacteria, y, in terms of time, x, if it doubles every second.

If the population starts with y0 bacteria and doubles every second, the number after x seconds is
y = y0 · 2^x.
If you start with 1 bacterium, y = 2^x.

Equivalently (continuous exponential form),
y = y0 · e^{(ln 2) x},
since ln 2 is the continuous growth rate giving a doubling time of 1 second.
