ELIBIBLE CONTENT:
A2.1.3.1.1: Write and/or solve quadratic equations
(including factoring and using the Quadratic
Formula).
A2.1.3.1.2: Solve equations involving rational
and/or radical expressions (e.g., 10/(x + 3) + 12/(x –
2) = 1 or √( x2 + 21x) = 14).
A2.1.2.2.1: Factor algebraic expressions, including
difference of squares and trinomials (trinomials
limited to the form ax2+bx+c where a is not equal
to 0).
A2.2.2.1.1: Create, interpret and/or use the
equation, graph or table of a polynomial function
(including quadratics).
A2.2.2.1.3: Determine, use and/or interpret
minimum and maximum values over a specified
interval of a graph of a polynomial, exponential or
logarithmic function.
Solving a quadratic equation by graphing,
factoring, or the quadratic formula.
Relating the graph and function of a
quadratic function that has 0, 1, or 2
zeros.
Relate the discriminant to the type and
number of solutions of a quadratic
equation.
Continue using computations with real,
imaginary, and complex numbers.
Student Objectives (Competencies/Outcomes):
Students will be able to:
 Graph quadratic functions in standard form
and find the max and min points.( 2 days)
 Identify the domain and range of quadratic
functions. ( contained in #1)
 Solve quadratic equations by:
 factoring, ( 2 days)
 taking the square root, ( 1 day)
 completing the square ( 2 days)

number and type of roots for a quadratic
equation. ( 2 days)
 Solve real-world problems, which are
modeled by quadratic functions. (2 days)
 Graph and analyze (state domain and range)
square root functions. ( 2 days)
Essential Questions:
 How can you extend algebraic properties
and processes to quadratic, exponential and
polynomial expressions and equations and
then apply them to solve real world
problems?

What are the advantages/disadvantages of
the various methods to represent
exponential functions (table, graph,
equation) and how do we choose the most
appropriate representation?
