An inequality is an expression where you don’t have equal signs.
Rather, you use >,<,≥,≤
To solve, you must give intervals of X that satisfy the inequality truths
Example Via Graphing
For example:
2x^3 + x^2 - 6x - 2 ≥ 0
Satisfy the inequalities by finding the X Intervals Above OR Equal to zero.
- Find the roots.
- Then, look at the graph and find where X is ≥ 0.
- The intervals are: -1.837⇐x⇐-0.327 U x>1.664
