Task: Students will learn about a polynomial function that measures the amount of ibuprofen in a patients bloodstream, as a function of time. After analyzing this function and graph, students are given another similar scenario, modeled by a quadratic function. Students will find the zeros (by factoring) and the vertex point to answer questions about this medication and its concentration in the bloodstream as a function of time.

 

Algebra Skills:

  • Analyzing zeros of a graph.
  • Substituting values into a function.
  • Solving a quadratic function by factoring.
  • This project does NOT require prior work with polynomial functions higher than 2nd degree quadratics.
