Then solve the function and get the answer. 1 Bacteria can multiply at an alarming rate when each bacteria splits into two new cells thus doubling. In this tutorial learn how to turn a word problem into an exponential decay function.

Exponential decay is generally applied to word problems that involve financial applications as well as those that deal with radioactive decay medicine dosages and population decline. To decay exponentially means that the topic being studied is decreasing in proportion to the amount that was previously present. David owns a chain of fast food restaurants that operated 200 stores in 1999.

If something decreases in value at a constant rate you may have exponential decay on your hands. A general formula that can be used to solve various types of exponential problems is. One real-life purpose of this concept is to use the exponential decay function to make predictions about market trends and expectations for impending losses.
