💡 Inequality Symbols & Graph Reference

  • Open Circle (hollow circle): Indicates that the boundary value is NOT included in the solution interval ($>$ or $<$, exclusive).
  • Closed Circle (solid circle): Indicates that the boundary value IS included in the solution interval ($\ge$ or $\le$, inclusive).
  • Quadratic Inequality: Represents the intervals where the parabola $y = ax^2 + bx + c$ lies above the x-axis ($>0$) or below the x-axis ($<0$). The boundary points are determined via factoring or the quadratic formula.
