3. Find an equation of a parabola with a vertex at the origin and directrix y = -3.5
Lina20 [59]

Answer:

y=\frac{1}{14}x^2

Step-by-step explanation:

we know that

The directrix of the parabola is perpendicular to the axis of symmetry of the parabola

In this problem  the directrix is y=-3.5

so

The axis of symmetry is parallel to the y-axis

we have a vertical parabola

Also, the vertex is at the origin

That means-----> the parabola open upward

The equation of a vertical parabola can be written as

x^2=4py

where

p is the distance between the vertex and the directrix

In this problem

the distance between the vertex and the directrix is 3.5

p=3.5 ----> the value of p is positive because the parabola open upward

substitute

x^2=4(3.5)y

x^2=14y

isolate the variable y

y=\frac{1}{14}x^2
