To find: the equation of the parabola.
Answer to Problem 43E
The equation of parabola is
Explanation of Solution
The equation of parabola is
Given information:
From the figure provided in the question it can be observed that
Directrix
The graph of parabola opens to the left.
Calculation: from the given directrix it can be observed that the parabola has horizontal axis.
So the equation of parabola should be in the following form,
For parabola with horizontal axis, directrix is
To comparing the directrix it can be observed that,
So the equation of parabola is,
Hence, the equation of parabola is
