Answer:
B,D,E for sure
Step-by-step explanation:
Not A because a parabola looks different. Not sure about C.
 
        
             
        
        
        
without changing units, since we can have a lbs:oz ratio, and that's perfectly fine

 
        
             
        
        
        
For this case we have the following function:
 
 To find the maximum of the function, what we should do is to derive the equation.
 We have then: 

 We match zero: 

 We clear the value of x: 

 We substitute the value of x in the function to find the maximum: 

 Rewriting: 
 Answer:
 a formula in terms of a for the maximum of f (x) is:
