Understand and use the symbols <, ⩽, >, ⩾

Solve linear inequalities in one variable, expressing solutions on a number line using the conventional notation.

e.g. \(2x + 1 \geq 7\)



\(1 < 3x-5 \leq 10\)



Solve quadratic inequalities in one variable.

e.g. \(x^2 - 2x < 3\)

Express solutions in set notation.

e.g. \(\{x : x \geq 3\}\)

\(\{x : 2 < x \leq 5\}\)
