# Exponential decay algebra 1 write a formula We do not want to set the problem up to compound monthly. Next, in the L1 column, enter the x-coordinates, 2 and 5. The graph is an example of an exponential decay function. This rapid growth is what is meant by the expression "increases exponentially". Note that this exponential function models short-term growth. As the inputs get larger, the outputs will get increasingly larger resulting in the model not being useful in the long term due to extremely large output values.

Investigating Continuous Growth So far we have worked with rational bases for exponential functions. And we can verify that that's the expression that we want. Solution: The yearly growth rate is the percent of increase. Solution: The diagram below shows how a monthly growth factor is multiplied 12 times throughout a 1 year period.

### Exponential function calculator

It could be 3 times r to the first power, or we could just write that as 3 times r. Thus, the information given in the problem can be written as input-output pairs: 0, 80 and 6, Solution: The diagram below shows how the yearly growth factor is multiplied 5 times throughout a 5 year period. And they tell us what g of 0 is. The population of gnats increases yearly at a constant rate. It is for this reason that the question is asking for an equation to approximate the population in terms of the monthly rate of growth. And let me just verify that that's what I did there. Press [STAT] again. We do this by expressing the exponent t as which equals t.

Try to choose points that are as far apart as possible to reduce round-off error. Solution Follow the guidelines above. Clear any existing entries in columns L1 or L2.
