Question

find the equation of the parabola whose end points of latus rectum are (-7/2,3) and (-7/2,-5) passes through (-2,-5)?

Answer 1

that two point is the latus rectum

Answer 2

so how can i get the distance of the latus rectum?

Answer 3

okay the distance is square root of 4 =2units, am i right?

Answer 4

8 units :)

Answer 5

thank you and how about the vertex how can i get it

Answer 6

it is horizontal

Answer 7

yeah that why im confused too, huhuhu,, maybe we have to ignore (-2,-5)

Answer 8

my teacher just gave it, and i just copied,, is there any way to find the answer?

Answer 9

:( i really dont get it,, so i have to get the slope and the y intercept?

Answer 10

-5=a(4) +h(-2) + c?

Answer 11

help

Answer 12

so i can use the elimination method?

Answer 13

:( help

Answer 14
