Population Growth and Decay using Differential Equations

WebBoth exponential growth and decay functions involve repeated multiplication by a constant factor. However, the difference lies in the size of that factor: - In an exponential growth function, the factor is greater than 1, so the output will increase (or "grow") over time. - In an exponential decay function, the factor is between 0 and 1, so the ... WebSolution: Here there is no direct mention of differential equations, but use of the buzz-phrase ‘growing exponentially’ must be taken as indicator that we are talking about the situation f(t) = cekt where here f(t) is the number of llamas at time t and c, k are constants to be determined from the information given in the problem. most after wanted 2019 pl

WebOne convenient use of "f (x)" is that we can use separate equations/functions and not confuse ourselves. e.g.: f (x) = 3x + 4. g (x) = (1/2)x - 2. If we used y, then we could get confused by whether or not we were talking about the same equation/function. So using function notation removes the confusion there.
