5.4B  Application of Quadratic Modeling

Application of Quadratic Modeling

    In previous lessons, we applied what we learned about linear modeling to word problems.

    We are now going to do the same for quadratic functions. 

   This section will be a very brief introduction to solving quadratic word problems. 

    We will work with various types of word problems later in the course. 

    This concept is very important as you will be doing oodles and oodles of optimization problems in calculus.   

Problem 1   

    Find the Quadratic equation that best models the data.

   The following data represents the average maximum and minimum temperatures recorded each month in Raleigh, NC, over 6 months. 

   The temperatures recorded are in degrees Fahrenheit.

Problem 2  

This data represents the money in Sam's savings account over the years.

Problem 3

   A biologist took a count of the number of fish in a particular lake, and

   recounted the lake's population of fish on each of the next six weeks.
