The alternate PSAT was conducted on 28th October 2015. This was the second official PSAT test and gives us a peek in to what Collegeboard has in store for the administration of the new SAT in 2016. Here are my video explanations to all of the math questions in the 2015 PSAT/NMSQT test. These are only available to subscribers.
Revised SAT Math: Domain of functions
Try the following SAT math question for the Revised SAT on domain of functions.
What is the domain of the function $f$, defined as $f(x)=\dfrac{x}{1+x^2}$ ?
- $\quad x \geq 0 $
- $\quad -1 \leq x \leq 1$
- $\quad \textrm{All real numbers}$
- $\quad \textrm{All real numbers except $-1$}$
Revised SAT Math: Linear equations and rearrangements
Try the following SAT math question for the Revised SAT that deals with linear equations and rearrangement of expressions:
$$R = \dfrac{7}{24}(F-32) + \dfrac{15}{2}$$
The formula above gives the conversion of temperature measured in Fahrenheit, $F$, to degrees Roemer, $R$. Which of the following equations could be used to convert temperatures from degrees Roemer to Fahrenheit?
- $\quad F = \dfrac{24R-11}{7}$
- $\quad F = \dfrac{4(6R+11)}{7}$
- $\quad F = \dfrac{24R}{7}-11$
- $\quad F = 3R+ \dfrac{19}{2}$
