Question

after a baby was born she began to gain weight at a rate of 2lbs pee month. the weight of the baby at birth was 8lbs. write an equation for W in terms of representing weight in pounds of the newborn baby t months after birth​

Answer 1

The required function is:
`W(t) = 2t+8`

Explanation:

The weight of the baby increases 2lbs per month which means that it is a linear function.

Now given that the initial weight was 8lbs it will remain constant.

Let t be the number of months and as the weight gain is 2 lbs per month, 2t will be the weight gain after t months.

The function can be written as:

`W(t) = 2t+8`

Hence,

The required function is:
`W(t) = 2t+8`
