Answer:
D
Step-by-step explanation:
 
        
                    
             
        
        
        
Let y = √4+7t 
then u= 4+7t 
y=√u = u^½
du/dt= 7 
dy/du = ½U^-½ 
dy/dt = du/dt • dy/du 
= 7×½U^-½ 
= 7/2√U
= 7 / (2{√4+7t})
        
             
        
        
        
The answer is C) y = 4x - 3
B and D can be eliminated by substituting 0 for x in each...the result is not -3
Now you have a 50/50 chance of getting the question correct
