[Video] Q7: For the function f, the table above shows some values of x and their corresponding values of f(x) in terms of the constants a, b, and c. if a < b < c, which of the following could not be the graph of y =f(x) in the xy-plane?

Explanation for Question 7 From the Math (No Calc) Section on the 2018 May Sat

Question seven says for the function AF the table above show some values of 2 X and their corresponding values of F of X in terms of the constants, 3 a, B and C, if C is greater than B, 4 which is greater than a, which of the following could not be the graph 5 of Y equals F of X in the X, 6 Y plane. So if a, 7 B and C are getting progressively greater, 8 that means that this function should be increasing because as the X value goes 9 up, so does the Y value, which means that whichever answer doesn't 10 fit here or whichever is the correct answer, 11 because it can't be the graph of Y equals F of X must not 12 be increasing at positive X values. 13 So let's go through each answer choice a as the X value increases, 14 the Y value increases. So this is not the correct answer. 15 This totally could be the graph of Michael's effects. 16 B however is decreasing. 17 And therefore B is the correct answer. 18 It can't be the graph of white equals F of X.
