Values of y that can make the inequality y < -4 true is y ε (-∞, -4).
How to solve inequality.
An inequality is a mathematical statement comparing the relative size of two expressions, typically using symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).
We want to find,
the values that make the inequality y<-4 true.
Given that,
i.e. it clear that
y ε (-∞, -4)
(y) can take any real number less than -4, approaching but never reaching -4.
The interval notation (-∞, -4) describes this set of values.
Values of y that can make the inequality y < -4 true is y ε (-∞, -4).
