This is true. Always start from -1, go to -2, and then move back up to 2 from 0. Let's make and b -1. -1 + 2 < -1 + 3 1 < 2. Okay that works. Let's try -2. -2 + 2 < -2 + 3. Let's use 0 now. 0 + 2 < 0 + 3 2 < 3 Now let's use 1. 1 + 2 < 1 + 3. 3 < 4. Let's use 2. 2 + 2 < 2 + 3 4 < 5. Your answer is A.) However, if the value of a and b change, then it is false.
