For each of the following functions find the inverse of the function. How to solve word problems involving exponential functions. In today’s scenario, even a 7-year-old child is seen holding a smartphone. Another application of the exponential function is exponential decay, which occurs in radioactive decay and the absorption of light. The graph of an exponential function (a parent function: one that isn't shifted) has an asymptote of . Most of us might have heard about the world’s worst invasive weed- Water Hyacinth. Applications of Exponential Functions AlgebraLAB. A summary of the problem focus was inserted before each problem, so that the student would be able to identify the problem focus without difficulty. One of the more interesting facts about this particular logarithmic scale is that it's related to the length of the fault line. O primeiro é o importante passo que estamos dando na criação de um corredor cultural no Norte do país. São duas décadas de produção intensa com cerca de 45 óperas realizadas, além de musicais, recitais e concertos de encerramento que havia todos os anos.
