How much did the puppy weight at birth?

The puppy weighed 6 pounds at birth.

Step-by-step explanation:

First, we can see that the puppy gains weight in a steady pace of 2.5 pounds every week :

4 weeks : 16 pounds

4x2.5 = 10 pounds

16 pounds - 10 pounds, because 0 weeks means starting at 0 years old. 16 - 10 = 6 pounds.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
