Question

What is the value of p in the equation y2=-4x? p=?

Answer 1

y^2 = 4px
y^2 = -4x
4p = -4
p = -1
hugs

Answer 2

the value of p=-1

Explanation:

General equation of a parabola is

`y^2= 4p(x)` where vertex is at (0,0)

now we compare the given equation with general form

`y^2=-4x`

We have -4 in the place of 4p

`4p=-4`

Divide both sides by 4

so p = -1

the value of p = -1
