NY State Math Algebra II Functions Practice

NY State Math Algebra II Functions. Practice it free.

Per the NYSED Algebra II Educator Guide blueprint, the Functions conceptual category is 38%–45% of credit and includes the domains Interpreting Functions (F-IF), Building Functions (F-BF), Linear, Quadratic, and Exponential Models (F-LE), and Trigonometric Functions (F-TF). This Algebra II reporting domain maps to 39 practice skills and 8 representative questions from the playable bank.

How the NY State Math reports it

New York’s Grades 3–8 math tests and Regents math exams are state-developed assessments rather than a shared national framework. The grades 3–8 exams are aligned to New York State learning standards, and the Regents math sequence includes Algebra I, Geometry, and Algebra II, with the June 2026 Algebra II exam explicitly based on the New York State Next Generation Learning Standards.

Blueprint & weighting

Grades 3–8: the official page and the retrieved administration guide describe item/credit structure and timing, but no published domain-by-domain blueprint weighting was located in the primary sources used here. Regents (high school): NYSED publishes a per-conceptual-category 'percent of test by credit' blueprint for each course in its Educator Guides. Algebra I — Number & Quantity 4%–10%, Algebra 48%–61%, Functions 24%–32%, Statistics & Probability 7%–15%. Geometry (single conceptual category, by domain) — Congruence (G-CO) 27%–34%, Similarity, Right Triangles, & Trigonometry (G-SRT) 29%–37%, Circles (G-C) 2%–8%, Expressing Geometric Properties with Equations (G-GPE) 12%–18%, Geometric Measurement & Dimensions (G-GMD) 2%–8%, Modeling with Geometry (G-MG) 8%–15%. Algebra II — Number & Quantity 4%–8%, Algebra 30%–39%, Functions 38%–45%, Statistics & Probability 14%–22%.

Convert $\dfrac{\pi}{6}$ to degrees.

$\dfrac{\pi}{6} \times \dfrac{180°}{\pi} = 30°$ .

What is $\tan\left(\dfrac{7\pi}{4}\right)$ ?

The reference angle for $\dfrac{7\pi}{4}$ is $\dfrac{\pi}{4}$ . Tangent is negative in Quadrant IV, so $\tan\left(\dfrac{7\pi}{4}\right) = -\tan\left(\dfrac{\pi}{4}\right) = -1$ .

A forest preserve had $4{,}000$ acres of woodland in $2010$ . Each year from $2010$ through $2020$ , a model estimates that the woodland area decreased by $5\%$ of the area the previous year. Which equation defines this model, where $a(t)$ is the estimated woodland area, in acres, $t$ years after $2010$ ?

The starting area is $4{,}000$ acres, and a $5\%$ yearly decrease means multiplying by $0.95$ each year, so $a(t) = 4{,}000(0.95)^t$ .

For which value of $x$ does the graph of $y = (x - 15)(x + 7)$ intercept the $x$ -axis?

Set $y = 0$ : $(x - 15)(x + 7) = 0$ . The zeros are $x = 15$ and $x = -7$ . Of the choices, $15$ is an x-coordinate of an x-intercept.

The equation of a line is $2x + 6y = -18\textsf{.}$ What is the $x$ -intercept of the line?

The $x$ -intercept is the value of $x$ when $y = 0\textsf{.}$ Substituting gives $2x = -18\textsf{,}$ so $x = -9\textsf{.}$

The function $r$ is defined by $r(t) = 60(1.09)^{t}$ . The function models the number of registered runners in a charity race $t$ years after the first race. Which statement is the best interpretation of the growth factor $1.09$ in this context?

The growth factor is $1.09$ . Each time $t$ increases by $1$ , the number of runners is multiplied by $1.09$ . That means each year the number of runners is $109\%$ of the previous year's number, a $9\%$ increase.
