I don't really understand how I would do this...

Create a polynomial model for the low temperature each day in your town throughout the year.

Research the daily low temperature each day in your town.
Choose five temperatures spread across the four seasons.

Create a quartic model using regression.
Graph the points and regression model on the same graph.

Create a quartic model using matrices.
Graph the points and matrix model on the same graph.

Compare the two models: Are they identical or slightly different?
Do both models pass through all five points?

perl · Answer

ok im here

perl · Answer

you will need the data for low temps

perl · Answer

365 days of lowest temps

perl · Answer

well, actually just need 5 low temps which is distributed in the seasons
so

perl · Answer

how about you divide 365 evenly by 5

anonymous · Answer

How would I graph it though?

perl · Answer

first give me the 5 data points

perl · Answer

so spread the 75 days apart from each other , you can start from january 1

perl · Answer

err, 73 days apart 
365/5

anonymous · Answer

so you have your 5 data points?

anonymous · Answer

My five points are 35.5, 51.2, 70.9, 52.2, and 37.6 all in degrees Fahrenheit.
