How to Write an Exponential Function: Word Problems
To write an exponential function from a word problem, find two things: the starting amount a and the factor b that multiplies the quantity each period. For growth of r percent, b = 1 + r; for decay of r percent, b = 1 − r. Then write y = a·bˣ. For example, $500 growing […]
