Answer: undefined in both cases.Explanation:1) Expression to evaluate: 

2) You are asked to evaluate that expression for two different cases, 
x = 0 and x = 3.3) First case:
 x = 0The expression cannot be evaluated at x = 0, because the 
denominators (both  denominators) 
equal 0, and the division by 0 is not defined.
So, the answer is 
undefined.
4) Second case, 
x = 3When you replace x = 3 you get:

Again, this result in a 
division by 0, so you conclude that it is
 undefined too.
 
 
        
             
        
        
        
Answer:
0 and -2 
Step-by-step explanation:
try that that should work for you even if you have a dad that dose not trust you 
 
        
             
        
        
        
N(2x+y) = x +1 
Differentiate both sides, using the Chain Rule on the left side. 
(1 / (2x + y)) * d(2x + y)/dx = 1 
(1 / (2x + y)) * (2 + dy/dx) = 1 
<span>Rearrange to isolate dy/dx.
