MO MAP Algebra II Functions Practice

Functions skills

Standards basis

Missouri Learning Standards (Mathematics K-5 and Mathematics 6-12; revised standards approved April 19, 2016) — Missouri

How the MO MAP reports it

Missouri’s MAP math is built from the Missouri Learning Standards and the state’s item specifications, not from a separate national testing framework. The standards are closely CCSS-aligned in structure, with grade-level and course-level domains used as the native reporting/coverage structure.

Blueprint & weighting

Missouri publishes grade-level and EOC blueprints, but the accessible official pages in this pass did not expose the domain-by-domain percentage tables. The assessment page states that item specifications organize expectations by domains/strands and that blueprints are available for grade-level and EOC assessments.

The function $f$ is defined by $f(x) = 7x - 4$ . What is the value of $f(x)$ when $x = 3$ ?

Substitute $x = 3$ : $f(3) = 7(3) - 4 = 21 - 4 = 17$ .

The function $f$ is defined by $f(x) = \sqrt{2x + 1}$ . What is the value of $f(x)$ when $x = 4$ ?

Substitute $x = 4$ : $f(4) = \sqrt{2(4) + 1} = \sqrt{9} = 3$ .

For the function $p$ , $p(0) = 200$ . For each increase in $x$ by $1$ , the value of $p(x)$ decreases by $10\%$ . What is the value of $p(2)$ ?

Each step multiplies by $0.90$ . So $p(2) = 200 \cdot 0.90^2 = 200 \cdot 0.81 = 162$ .

$g = 9 - \dfrac{m}{4}$

The equation shown gives the estimated amount of paint $g\textsf{,}$ in gallons, remaining after covering $m$ square meters of wall, where $0 \le m \le 36\textsf{.}$ What is the estimated amount of paint, in gallons, remaining after covering $12$ square meters of wall?

Substitute $m = 12\textsf{:}$ $g = 9 - \dfrac{12}{4} = 9 - 3 = 6\textsf{.}$ The estimated amount remaining is $6$ gallons.

What is the value of $\log_{4}16\textsf{?}$

$4^{2} = 16\textsf{,}$ so $\log_{4}16 = 2\textsf{.}$

A $32$ -milligram sample of a radioactive isotope has a half-life of $1$ year.

Choose the function model that correctly calculates the amount remaining after $4$ years.

The remaining amount after $t$ years is $A(t) = 32\left(\dfrac{1}{2}\right)^{\textstyle\frac{t}{h}}\textsf{,}$ where $h$ is the half-life. Here $t = 4$ and $h = 1\textsf{,}$ so $A(4) = 32\left(\dfrac{1}{2}\right)^{\textstyle\frac{4}{1}} = 32\left(\dfrac{1}{2}\right)^{4} = 2\textsf{.}$

The function $D$ is defined by $D(t) = 1{,}500(0.6)^{t/5}$ . The function $D$ models the amount of a drug, in micrograms, in a patient's bloodstream, where $t$ is the number of hours after a dose is given. Which statement best describes what the factor $0.6$ represents in this model?

Every $5$ hours, the exponent increases by $1$ , so the amount is multiplied by $0.6$ . That means $60\%$ of the previous amount remains after each $5$ -hour interval.

You invest $\text{\char36}2000$ at $5\%$ annual interest for $1$ year. What is the total?

$2000 \times 1.05 = 2100$ .
