What does 'r' represent in the exponential growth equation W₁=W₀ e^ r t

Step-by-step solution

If we plot the parameter of growth against time, we get a typical sigmoid or S-curve. The exponential growth can be expressed as W₁=W₀ e^ r t W1 = final size (weight, height, number etc.) W0 = initial size at the beginning of the period r = growth rate t = time of growth e = base of natural logarithms
