To graph absolute value functions, plot … WebIf you take the absolute value of negative 3 and 1/4, you'll get positive 3 and 1/4, which won't work. 3 and 1/4 is greater than 2 and 1/2, so that's true, that works out. And same thing for 3. 2 times 3 is 6, minus 3 and 1/4 is 2 and 3/4. Take the absolute value, it's 2 and 3/4, still bigger than 2 and 1/2, so it won't work.
