UNIT6 OBJECTIVE 1 - EXPONENTIAL AND LOGARITHMIC FUNCTIONS
		
		An exponential function is any function of the form: 		
		where the base=b is positive, b is not equal to 1 and x is any real number.  A logarithmic function 
		is any function of the form:  where the base=b is positive, b is not equal to 1 and x>0 . 
		(It is read as "log, base b, of x")	
		The logarithm is a new function obtained by trying to solve for x. So 
		means the same as . 	The log is equal to the exponent for the base.		
		You can go back and forth between:  Exponential form logarithmic form 	
		And 

Example 1 Write the following in logarithmic form: a.is the same as b.is the same as Example 2 Write the following in exponential form: a. is same as .

b. is same as

If you have missing values in a simple logarithmic expression can be evaluated by rewriting the expression in exponential form using the fact that (When expressions have the same base then the exponents must be equal.) Example 3 Find N in each of the following: Rewrite 9=N
