Find a polynomial function to model each set of data.

Create a table to model each set of data.

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

$\"\"$

Create a scatter plot of the above data.

Draw a coordinate plane.

Plot the points obtained by from the table.

Connect all those points.

$\"\"$

Observe the above graph :

The polynomial function represents a straight line.

Find the polynomial function by using the points $\"\"$ and $\"\"$ .

Let the points are $\"\"$ and $\"\"$ .

The line equation passing through the points $\"\"$ and $\"\"$ is $\"\"$ .

The line equation passing through the points $\"\"$ and $\"\"$ is :

$\"\"$

Thus, the polynomial function is $\"\"$ .

$\"\"$

Thus, the polynomial function is $\"\"$ .
