Answer: (0,2)
Step-by-step explanation:
We know that the general equation of a parabola with vertex at the origin and vertical orientation is given by
, where a is the distance between the vertex and the origin.
The focal point = (0,a)
Given: Yung is designing a flashlight that uses a parabolic reflecting mirror and a light source.
The shape of the mirror can be modeled by :-
, where x and y are measured in inches.
⇒ The focal point = (0,2)
Hence, the focus point of the flashlight = (0,2)
