(NCTM) 1. Understand patterns, relations, and functions • analyze functions of one variable by investigating rates of change, intercepts, zeros, asymptotes, and local and global behavior; • interpret representations of functions of two variables 2. Represent and analyze mathematical situations and structures using algebraic symbols • use symbolic algebra to represent and explain mathematical relationships 3. Use mathematical models to represent and understand quantitative relationships • identify essential quantitative relationships in a situation and determine the class or classes of functions that might model the relationships |
