a designer wants to create a whisper chamber in the shape of an ellipse. he has a warehouse space with a longest length of 30 ft, which he decides will be the major axis of his elliptical chamber. he determines the best spots for his guests to stand to experience his whisper chamber will be 4 ft from the center of the warehouse space, which will act as the foci. how far out from the center, along the minor axis, should he build his whisper chamber?

29.7 ft
28.9 ft
14.5 ft
7.2 ft

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
