### Requirements

Students solve two problems modeled by quadratic equations. One problem involves profits from a business and the other, water draining from a bathtub. Students graph quadratic equations and use their graphs to answer questions. Quadratic Word Problems Part 2 is the second of four activities for teaching and learning quadratic equations in algebra: Graphing Quadratic Equations; Quadratic Word Problems Part 1; Quadratic Word Problems Part 2; and Quadratic Functions in Vertex Form.

» Lesson Plan and Student Assessment documents are also available.

### COMMON CORE STATE STANDARDS FOR MATHEMATICS (2010)

CCSS.Math.Content.HSF-IF.B.4 For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.

CCSS.Math.Content.HSF-IF.C.7 Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.

CCSS.Math.Content.HSF-IF.C.7a Graph linear and quadratic functions and show intercepts, maxima, and minima.
