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

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

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 $p(2)$?

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

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?

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?

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

The function $h$ is defined by $h(t) = -16t^{2} + 64t + 5$. The function models the height, in feet, of a baseball $t$ seconds after it is hit. Which of the following is the best interpretation of the statement "$h(2)$ is equal to $69$" in this context?
