Company ABC found that the yearly revenue and cost can be modeled by the following  functions of x where x is thousands of units:      2 R (x) = 30 x  –  0.5 x     and    C (x) = 20 x – 153    Find the number of units Company ABC must produce and sell to maximize the yearly profit  and find the maximum yearly profit.     Revenue, Cost , and Profit are in thousands of dollars.

Solution 1: 
 ( )            
For Y intercept:
Hence  
 ( )    
Hence Y intercept is 0 
For X intercept: 
 ( )    
Hence
 (       )    
 (   )
Solution 2: 
  ( )            
Critical points: 
  ( )
(   )(   )
Increasing: 
  (     )  (    ) 
Decreasing: 
  (     ) 
Relative maxima: 
 (  )            
 (  )                
Hence relative maxima occurs at x=-3 
Relative Minima: 
 (  )         
 (  )     
Relative minima occurs at:
Solution 3: 
   ( )        
Critical numbers: 
   ( )
Concave up: 
   (  )            
  (    ) 
Concave down: 
   (  )             
  (     ) 
Point of inflection is:
Solution 4:
Solution 5: 
For Y intercept : 
  X=0 
   ( )   
 
 

For X intercept: 
  Y=0 
 ( )    
   
   

Solution 6: 
Vertical asymptote:
Horizontal Asymptote:
Solution 7:
