Question

What is an equation of a parabola with a vertex at the origin and directrix x = 4.75?

Answer 1

\[x^2=-4py\] with \(p=4.75\)

Answer 2

since vortex is at the (0,0) so
y^2=-4px
p=4.75
y^2=-19x

Answer 3

So what am i susposed to do ?

Answer 4

@sami-21 is right and i am wrong
i got the square wrong

Answer 5

\[y^2=-19x\]

Answer 6

So would it be -1/19y^2 ?

Answer 7

if you solve for \(x\) it would be
\[x=-\frac{1}{19}y^2\] yes

Answer 8

yes thank you. Can you have help with 3 more ?
