CLICK "CHOOSE A STUDY MODE" OR "OPTIONS" TO LEARN AND PRACTICE IN DIFFERENT WAYS
IN THIS UNIT, STUDENTS WILL BE EXPECTED TO:
 Determine if a relation is a function, identify domain and range, identify why a domain is appropriate for the context, and evaluate
functions for a given value of x.
 Determine appropriate units for labels and scale of a graph and use these to graph on a coordinate axes, by hand and using
technology, recognizing that the graphical representation of an equation in two variables is a line or a curve and why each point
on the line or curve is a solution to its equation.
 Choose an appropriate method for solving quadratic equations, to include inspection, taking square roots, completing the square,
factoring, and quadratic formula.
 Compare properties of two functions represented in different ways.
 Define and recognize the key features in tables, graphs and equations, such as intercepts, end behavior, intervals of
increase/decrease, symmetry, and relative minimum/maximum values.
 Identify the effect transformations will have on a function.
 Identify ways to rewrite expressions based on the structure of the expression to reveal and explain properties of the expression
using methods such as factoring and completing the square.
 Derive the quadratic formula and use the discriminant to describe the nature of the solutions of a quadratic equation.
