Answer to Problem 13CYU
The
Explanation of Solution
Given:
The focus is 6 feet above the vertex and the latus rectum is 24 feet along.
Calculation:
Consider the general vertex form is,
The value of the latus rectum is 6 feet above the vertex and the latus rectum is 24 feet long. Then the value of a is,
The focus of the parabola is at the origin, then then, the coordinates of the focus are,
The equation of the parabola is,
(b)
To find: The graph for the parabola.
