Question

Please I need help. Don’t understand

Answer 1

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.
