Explanation for Question 28 From the Math (Calc) Section on the 2019 May Sat
So question 28 states for the function F if F of three X is 2 equal to X minus six, for all values of X, 3 what is the value of F of six? 4 So for this, you need to know that you can rewrite F of 5 six as F of three 6 times two. And since we know that F of 7 three of X is equal to X minus six, 8 that means F three times two will just be plugging into 9 for ax. So all we have to do is plug into for X in 10 the X minus six, and that gives us two minus six is 11 equal to negative four. So that means that the answer here is B.
