There is a formula that estimates how much your puppy will weigh when it reaches adulthood. The method we present applies to medium-sized breeds. First find your puppy's weight w, in pounds, at an age of weeks, where a is 16 weeks or less. Then the predicted adult weight 
W = W(aw),
 in pounds, is given by the formula
W = 52
(a) Use functional notation to express the adult weight of a puppy that weighs 4 pounds at 11 weeks. 

(b) Calculate the predicted adult weight for the puppy from part (a). (Round your answer to two decimal places.)

Hi there! Thank you for the opportunity to help you with your question!

The function W now has two arguments, w (measured in pounds) , and a (measured in weeks)

(a) for a pup that weighs 4 pounds at 11 weeks, we are calculating W(11, 4)

(b) we plug in the values 11 and 4 into the expression

52^(4/11) = 4.21 lbs 

Please let me know if you need any clarification. Always glad to help!
