Explanation for Question 3 From the Math (No Calc) Section on the 2019 April Sat
For a number three, we are given the function F of X equals two 2 times X minus one, plus two. And we want to know what the value 3 of F of one is. So what this question is basically asking is what 4 is the value of Y when X is equal to one F of X 5 is just another fancy way of writing Y so we can plug in F 6 of one equals two, 7 we plug in one for X, and that gives us one minus one. 8 Plus two, one minus one is zero and two times 9 zero is still zero. So that's going to get rid of that term, 10 which leaves us with F of one is equal to two, 11 which is B.
