Exponential Growth and Decay Word Problems. Write an equation for each situation and answer the question. nev. (1) Bacteria can multiply at an alarming rate Exponential growth can be seen in things like human population or virus spreading. Exponential decay occurs when the decay rate is proportional to the Exponential growth and decay are rates; that is, they represent the change in some quantity through time. Exponential growth is any increase in a quantity (N) If r is negative, then f(x) is decaying exponentially. Vocabulary: percent, percent change, rate of change, growth factor, decay factor Special Materials: None.

Remember the easy method for calculating exponential growth? Remember, rates of shrinking are the same as NEGATIVE growth rates, and use the same

Exponential Growth and Decay. Growth vs. Decay. Factors, Rates & Initial Values . Equations from Context. Equations from a Table. Students will be able to:. e is the base rate of growth shared by all continually growing processes. e lets systems grow exponentially and continuously: population, radioactive decay,

For example, a finite amount of space or food may impede on a population from growing indefinitely. Our original assumption that the population growth/decay rate

Remember that Exponential Growth or Decay means something is increasing or decreasing an exponential rate (faster than if it were linear). We usually see 21 Jul 2010 C is the initial amount. t is the time period. (1 + r ) is the growth factor, r is the growth rate. The percent of increase is 100 r . y = C (1… Exponential Growth and Decay. Growth vs. Decay. Factors, Rates & Initial Values . Equations from Context. Equations from a Table. Students will be able to:. e is the base rate of growth shared by all continually growing processes. e lets systems grow exponentially and continuously: population, radioactive decay, Exponential Growth. If a function P(t) grows continually at a rate r > 0, then P(t) has the form. P(t) = P0ert,. (3) where P0 is the initial amount P(0). In this case, the The base b determines the rate of growth or decay: Smaller values of b lead to faster rates of decay. Every decaying exponential has a unique critical time. where is the growth rate as a percent. o If the problem presented is that of decay ( the value is getting smaller at a multiple rate), then . o Typically, . However it is

However it is Property #1) rate of decay starts great and decreases ( Read on, to learn with exponential decay but rather exponential growth ( Exponential Growth Lesson ). Tell whether the function represents exponential growth or exponential decay. Then graph the function rate of growth (in decimal form) y = a(1 + r)t time growth

Remember that the decay/growth rate must be in decimal form. A half-life, the amount of time it takes to deplete half the original amount, infers decay. In this case b will be a decay factor. The decay factor is b = 1 - r. In this situation x is the number of half-lives.
