F(−2)=14. Explanation: substitute x=− 2 into f(x). f(−2)=(3×(−2)2)−(−2). ××=(3×4)+2=12+2=14 .
        
                    
             
        
        
        
Answer:
 
.
Step-by-step explanation:
We have been given that 4 days I have 140 copies of a book, 9 days I only have 50 left. We are asked to write an equation 
, where c is number of copies still on hand and t days being available. 
We have two points on line (4,140) and (9,50). Now, we will use these points to find slope as:



Now, we will use point-slope form of equation 
 and substitute 
 and coordinates of point (9,50) as:




Therefore, our required equation would be 
.
