Grade 11 Quadratic Equations and Expressions CCSS: HSG-GPE.A.2
Is the answer from the previous question the correct equation for the parabola with focus at (6,2) and directrix x=4? Why or why not?
- No, the vertex has not yet been found or given, and without this information one cannot find the equation.
- No, since there is a y2 term, but no x2 term.
- Yes, but the translation from the origin still needs to be accounted for.
- Yes, it's just in a different form (and can be put in the more common form by completing the square).
