alg I exponential test review guide

There is a test coming up on Exponential functions.



1 graphing an exponential function; know how to make a table a plot the points


2 scientific notation problems; one will involve operations with very large/small numbers


Some of the rules of exponent problems from the quiz will be on this; probably 3

1 problem on comparing 2 money models- (we did this twice in class)''

2 word problems on decay/ growth models

1 problem going from a data set/ table to equation

2 simplifying radicals


You don't have to memorize the formulas but you will have to know that growth is 1+r and decay is 1-r.
here is a link to a video on rules of exponents

here are a few samples:
1.  simplify the square root of 24 plus the square root of 54
2.  a town of 10000 grows at 1%.  How many people live there in 8 years.
3.  graph y=5(3) to the x.
4.  (3x)(-4x) =
5.  what is anything to the zero power?
6.  what is 5 to the negative 2 power/
