Part A To compare the linear functions, you first need to find their equations. For each of the linear functions, write an
equation to represent the puppy's weight in terms of the number of weeks since the person got the puppy.

Linear functions are used to illustrate functions that follow a straight line.

Amit's puppy

From the graph, we can see that the points are not on a straight line.

Hence, Amit's puppy is not a linear function.

Camille's puppy

From the graph, we have the following points:

Start by calculating the slope (m)

So, we have:

The linear function is the calculated using:

This gives

Expand

Simplify

Hence, the equation of Camille's puppy is

Olivia's puppy

From the table, we have the following points:

Start by calculating the slope (m)

So, we have:

The linear function is the calculated using:

This gives

Expand

Simplify

Hence, the equation of Olivia's puppy is
