Explanation The equation of a hyperbola centred at the origin with foci ( c , 0 ) and ( − c , 0 ) and x-intercepts ( a , 0 ) and ( − a , 0 ) is x 2 a 2 − y 2 b 2 = 1 where b 2 = c 2 − a 2 . The difference of the distance from any point on the ellipse to the two foci is 2 a . Since a = ± 4 , therefore the x-intercepts are ( 4 , 0 ) and ( − 4 , 0 )
