CPM Algebra 2 Chapter 1 Test Review

Vocabulary flashcards covering the standards, rubric levels, key mathematical concepts, and graphical analysis from the CPM Algebra 2 Chapter 1 Test Retake.

Standard AG4A

A curriculum standard titled "Reasoning with Equations & Inequalities" that assesses solving linear, rational, and factored polynomial equations, as well as factoring quadratic and multivariable expressions.

Standard FN1B

A curriculum standard titled "Interpreting functions" that evaluates finding function values (such as $f(9)$), solving for $x$ given a function value, and identifying the domain and range of graphed functions.

Standard AG1

A curriculum standard titled "Seeing structure in expressions" that focuses on isolating and solving for an indicated variable within literal equations.

Standard AG4B

A curriculum standard titled "Reasoning with Equations & Inequalities" focused on solving quadratic equations using the quadratic formula and rounding answers to the nearest hundredth ($2$ decimal places) when necessary.

Standard FN1A

A curriculum standard titled "Interpreting functions" requiring students to use a calculator to generate a table with at least $5$ integer values for both $x$ and $y$ and sketch a complete graph of given functions.

Standard FS1

A foundational curriculum standard titled "Algebra Foundations" covering core skills including formula rearrangement, radical simplification, evaluating expressions of the form $f(x) - c$, and factoring trinomials.

Rubric Score 0

The lowest performance level on the standard assessment rubric, defined as "Unable to assess."

Rubric Score 1

A performance level on the standard assessment rubric defined as "Limited understanding."

Rubric Score 2

A performance level on the standard assessment rubric defined as "Inconsistent."

Rubric Score 3

A performance level on the standard assessment rubric defined as "Consistent."

Rubric Score 4

The highest performance level on the standard assessment rubric, defined as "Detailed & High Level."

Graph 2a (Parabola Domain and Range)

An upward-opening parabola with a vertex at $(-2, -6)$ and $x$-intercepts at $(-6, 0)$ and $(2, 0)$, having a domain of all real numbers ($(-\infty, \infty)$) and a range of $[-6, \infty)$.

Graph 2b (Function $f$ Domain and Range)

A continuous curve beginning at an open endpoint at $(-3, 0)$, reaching a relative minimum at $(-2, -4)$, a relative maximum at $(0, 0)$, and terminating at a closed endpoint at $(1, -4)$, with a domain of $(-3, 1]$ and a range of $[-4, 0]$.

Quadratic Formula

The algebraic method used to solve equations of the form $ax^2 + bx + c = 0$, given by $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.

Difference of Two Squares

A factoring pattern of the form $a^2 - b^2 = (a - b)(a + b)$, demonstrated on the test by factoring the expression $25x^2 - 1$ into $(5x - 1)(5x + 1)$.

Literal Equation

An equation containing two or more variables (such as $C = \frac{2}{7}(F - 20)$ or $j = \frac{krp}{tm}$) where the objective is to rearrange and isolate a specified target variable.
