Nathan AxelTo solve the inequality -4 ≤ 3 - y and write it in interval notation:
-
Subtract 3 from both sides: -4 - 3 ≤ -y -7 ≤ -y
-
Multiply both sides by -1 to change the direction of the inequality: 7 ≥ y
-
Write it in interval notation: [7, ∞)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
