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
