Question

Which type of conic section has an eccentricity greater than one? a. an ellipse c. a hyperbola b. a parabola d. a circle

Answer 1

circle has eccentricity 0
ellipse between 0 and 1
parabola has 1
hyperbolae have eccentricity greater than 1

so, a hyperbola

Answer 2

Here are the figures you get with different values of eccentricity e.
  e = 0: circle
  0 < e < 1: ellipse
  e = 1: parabola
  e > 1: hyperbola

The conic section that has an eccentricity greater than 1 is ...
  c. hyperbola
