About This Worksheet
This medium-level worksheet contains 18 problems designed for 11th Grade students practicing parabolas. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.
Parabolas model projectile motion, reflector dish design (satellite dishes and headlights), and many optimization problems. The focus-directrix definition connects the algebraic equation to a geometric construction with profound optical applications.
- Write the equation of a parabola in standard form and identify the vertex, focus, and directrix
- Graph parabolas opening in any direction and interpret the focus-directrix definition geometrically
- Convert from general to standard form by completing the square
- Write the equation of a parabola given its focus and directrix
- Determine the focal length p from the standard-form coefficient
