Answer:
h'(1)=0
Step-by-step explanation:
We use the definition of the derivative of a quotient:
If  , then:
, then:

Since in our case we want the derivative of  at the point x = 1, which is indicated by: h'(1), we need to evaluate the previous expression at x = 1, that is:
 at the point x = 1, which is indicated by: h'(1), we need to evaluate the previous expression at x = 1, that is:

which, by replacing with the given numerical values:

becomes:

 
        
             
        
        
        
 
 
5/9 and 11/21
LCM of the denominators is 63
changing their denominators to all have a common denominator of 63:
5(7)/63 = 35/63
11(3)/63 = 33/63
from the above;
5/9 > 11/21.
