Answer:
(2, 9 )
Step-by-step explanation:
A translation of 4 units left is equivalent to subtracting 4 from the value of the x- coordinate, that is
(6, 9 ) → (6 - 4, 9 ) → (2, 9 )
 
        
             
        
        
        
Answer:
2,5
Step-by-step explanation:
(1+3)/2, (4+6)/2
 
        
             
        
        
        
Use the power, product, and chain rules:

• product rule

• power rule for the first term, and power/chain rules for the second term:

• power rule

Now simplify.

You could also use logarithmic differentiation, which involves taking logarithms of both sides and differentiating with the chain rule.
On the right side, the logarithm of a product can be expanded as a sum of logarithms. Then use other properties of logarithms to simplify

Differentiate both sides and you end up with the same derivative:
