Just plug in the same X values from function Y into function A then compare.
X Y(FunctionA) Y(Function B)
-9 5/3(-9) - 2 = -17 -7
3 5/3(3) - 2 = 3 1
9 5/3(9) - 2 = 13 5
From this, you can see that any number greater than 0 is going to be larger for function A than it is for function B. You can guess that anything bigger than 3 will be larger for A than B.
Therefore, the first statement is true.
