About This Worksheet
This hard-level worksheet contains 23 problems designed for 11th Grade students practicing parabolas. Hard worksheets feature challenging problems including multi-step questions, missing values, and real-world applications to push students further.
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
