P = P0 * e^kt

where where P0 and initial quantities

e = 2.71828

We say that P and Q are growing or decaying at a continuous rate of k. (For example, k =0 .02 corresponds to a continuous rate of 2%.)

what is the meaning of continuous rate and when we say it's a constant rate ?

see this please :

P = 5(1 .07)^s

in this other example the growth rate it 0.07 which is 7%

in the first example the growth rate was an exponent ! ( k value )

what changed ? how would the growth rate changing his places in a functions
