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

circle has eccentricity 0

ellipse between 0 and 1

parabola has 1

hyperbolae have eccentricity greater than 1

so, a hyperbola

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
