Grade 11 Quadratic Equations and Expressions CCSS: HSG-GPE.A.2
Using the equation found in the fourth question, what is the resulting equation once d1,d2 are substituted for the equations found for them in the previous two questions? Is this the final equation for a parabola with focus (h+p,k) and directrix x=h-p, or is more work needed?
- (y-k)2=4p(x+h) This is the final equation.
- (y-k)2=2h(p-2x) This is the final equation, but looks different than normal because the focus was (h+p,k) instead of (h,k).
- (y-k)2=4p(x-h) This is the final equation.
- (y-k)=4p(x-h)2 This is not the final equation, but it simply needs to be fully expanded and rearranged.
