Question

determine the equation of parabola with an axis parralel to y axis, vertex on x axis,,n which passes through point(2,3) and (-1,12)

Answer 1

This is easy man, what have you tried?

Answer 2

yes bt i dun have answers
im getting focus (11/5)
check if u get it

Answer 3

i got it it's easy

Answer 4

yehh i want to recheck my answer

Answer 5

wait i'm tapping...

Answer 6

presume y=ax^2+bx^2+c so b^2-4ac<=0

Answer 7

lol temme answer,

Answer 8

Sorry i went out

Answer 9

i'm back !! a=-3 or -1/2, b=0 or -5/2 c=15 or10

Answer 10

how did u get it

Answer 11

so y=-3x^2+15 or -1/2x^2-5/2+10

Answer 12

i mean how u took out focus, co ordinates

Answer 13

haha ~ presume y=k(x-b)^2+d(dismiss d since the vertexis on the x axis){another way of the equation of parabola },and use the equation of parabola above at the same time,you try it

Answer 14

okay with it?

Answer 15

grait job explaining it all frank

Answer 16

Thanks~
