This social-minded text opens with climate change, ends with climate change, and addresses issues of public health and income inequality in between. The sequence of problems generates intellectual need for students to develop important algebraic tools around functions and mathematical modeling: graphing linear equations, understanding the distributive property with algebraic expressions, solving systems of linear equations, reinforcing the algebra of exponents, understanding logarithms, solving quadratic equations, completing the square, and working with rational exponents. Students will see linear functions as modeling constant rates of change, exponential functions as modeling constant percent change, and quadratic functions as modeling constant acceleration. To drive home important modeling elements, the material introduces inverse functions and logarithms. Overall, the text sends a strong message to students that mathematics is a sense making tool that helps explain the world we live in.
