Answer:
Step-by-step explanation:
The given relation is
To make the subject, we square both sides of the equation to get;
Isolate on one side of the equation;
Or
We take the positive square root of both sides to get;
The directrix of the parabola is
The parabola equation is given as:
A parabola is represented as:
By comparing both equations, we have:
4p = 1/4 ==> p = 1/16
-k= 3 ==> k = -3
The directrix is represented as:
y = k - p
So, we have:
Take the LCM
Evaluate
Hence, the directrix of the parabola is
