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 35 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%.

Which is the Pythagorean identity?

The fundamental Pythagorean identity is sin2θ+cos2θ=1.\sin^{2}\theta + \cos^{2}\theta = 1\textsf{.}

For which value of xx does the graph of y=(x15)(x+7)y = (x - 15)(x + 7) intercept the xx-axis?

Set y=0y = 0: (x15)(x+7)=0(x - 15)(x + 7) = 0. The zeros are x=15x = 15 and x=7x = -7. Of the choices, 1515 is an x-coordinate of an x-intercept.

f(x)=(x9)22f(x) = (x - 9)^2 - 2

The function
ff is defined by the given equation. For what value of xx does f(x)f(x) reach its minimum?

The equation is in vertex form f(x)=a(xh)2+kf(x) = a(x - h)^2 + k with a=1>0a = 1 > 0, so the graph opens upward and the minimum occurs at the vertex. Here h=9h = 9, so the vertex is at x=9x = 9. Therefore, f(x)f(x) reaches its minimum when x=9x = 9.

The equation y=x2+4x+3y = x^2 + 4x + 3 models a quantity yy in terms of xx. For what value of xx is yy as small as possible?

The parabola opens upward, so the smallest yy is at the vertex. For y=ax2+bx+cy = ax^2 + bx + c, the xx-value at the vertex is x=b2ax = -\dfrac{b}{2a}. Here a=1a = 1 and b=4b = 4, so x=42(1)=42=2x = -\dfrac{4}{2(1)} = -\dfrac{4}{2} = -2. Therefore, yy is as small as possible when x=2x = -2.

What is tan(7π4)\tan\left(\dfrac{7\pi}{4}\right)?

The reference angle for 7π4\dfrac{7\pi}{4} is π4\dfrac{\pi}{4}. Tangent is negative in Quadrant IV, so tan(7π4)=tan(π4)=1\tan\left(\dfrac{7\pi}{4}\right) = -\tan\left(\dfrac{\pi}{4}\right) = -1.

A forest preserve had 4,0004{,}000 acres of woodland in 20102010. Each year from 20102010 through 20202020, a model estimates that the woodland area decreased by 5%5\% of the area the previous year. Which equation defines this model, where a(t)a(t) is the estimated woodland area, in acres, tt years after 20102010?

The starting area is 4,0004{,}000 acres, and a 5%5\% yearly decrease means multiplying by 0.950.95 each year, so a(t)=4,000(0.95)ta(t) = 4{,}000(0.95)^t.
