Question

PLEASE HELP!!!! The focus of a parabola is (−6,−3) . The directrix of the parabola is y=4.

What is the equation of the parabola?



y=−1/28(x+6)^2+1/2


y=−1/28(x−1/2)^2−6


y=−1/14(x+1/2)^2+6


y=−1/14(x+6)^2+1/2


The directrix of a parabola is y=−4. The focus of the parabola is (−2,−2) .


What is the equation of the parabola?



y=−1/4(x−2)^2−3


y=1/4(x+2)^2−3


y=−1/8(x+2)^2+3


y=1/8(x−2)^2−3


The directrix of a parabola is y=9. The focus of the parabola is (2,5).


What is the equation of the parabola?



y=−1/8(x−2)^2+7


y=1/8(x−2)^2−7


y=−1/8(x−2)^2−7


y=1/8(x−2)^2+7

Explanation:

Gregor Mendel knew how to keep things simple. In Mendel's work on pea plants, each gene came in just two different versions, or alleles, and these alleles had a nice, clear-cut dominance relationship (with the dominant allele fully overriding the recessive allele to determine the plant's appearance
