alg I exponential test review guide

There are 12 questions on the unit test.


4 simplifying expressions with either radicals or exponents
2 word problems using exponential functions
1 multiplying numbers in scientific notation
3 sequence problems (2 writing equations to match the sequence, 1 finding a term in the sequence)
1 finding the length of a line on a coordinate plane
1 graphing exponential functions


Here are some problems in the book, that address exponents, roots, sci-not and graphs of exp. functions.
p. 542 #4 all
p. 573 #5 all,
p. 588 #9a, d
p. 600 #1a,c,e,f,  #3 d, f

In addition to those, you should practice some word problems on exponential functions.

here are some:

a.  Eddie has a virus.  In fact he has 1 million virus cells in his body, though he is fighting it and killing 10% of them each hour.  Once the virus has less than 100 cells, it will be considered gone.  How many hours will it take to get rid of the virus?


b.   I have $10,000 invested in an account that gets 11.4% interest each year.  How much will I have in 18 years?


c.  If a town of 500 becomes 750 in 4 years, what is the rate of growth?
