Answer to Problem 13PPS

A puppy less than 6 months should be fed three times a day.|

a puppy between 6-12 months of ages should be fed 3 times a day.

A Puppy of age more than 6 months should be fed once a day.

Explanation of Solution

Given:

  

Calculation:

Consider the table that shows number of times puppies fed at different ages.

Days [x]	Age [y]
	Less than 6 months 6-12 months more than 12 months
1	3 2 1
2	6 4 2
3	9 6 3

The rate of change is change in one quality with respect to another quantity.

Mathematically:

  $Rateof\text{}\text{}\text{}\text{}change=\frac{change\text{}\text{}iny}{changeinx}$

Thus, the rate of change is change in age with respect to change in days.

So, the rate of change in feeding for the puppies less than 6 months is:

Rate of change = $\frac{4-2}{2-1}=2$

And, also the rate of change in feeding for the puppies more than 12 months is:

Rate of change = $\frac{2-1}{2-1}=1$

Conclusion:

Therefore, a puppy less than 6 months should be fed three times a day,a puppy between 6-12 months of ages should be fed 3 times a day. And also, the puppies of age more than 6 months should be fed once a day.
