There are two ways of classifying parabolas:
By the direction in which they are open: open at the top or at the bottom.
By the number of real roots: 2 real, 1 real or no real roots.

Do parabolas have to be curved?
yes
Which conic section has a directrix?
Parabolas have directori.
What are examples of real world parabolas?

Can two parabolas of the form with different vertices have the same axis of symmetry?
The form is not specified in the question so it is hard to tell. But two parabolas with different vertices can certainly have the same axis of symmetry.
Where can you find a picture labeled with 5 lines and 5 parabolas?

What are the Types of conic sections?
The types of conic sections are circles, parabolas, hyperbolas, and ellipses.
Why are the McDonald's arches considered parabolas?
Becuase a parabola is an arch shape so that is why the 'golden arches' are parabolas.
Do parabolas oscillate?
NO. They do not oscillate.
Do parabolas have to be curved?
yes
How are hyperbolas different from parabolas?
hyperbolas have an eccentricity (fixed point to fixed line ratio) that is greater than 1, while the parabolas have an exact eccentricity that is equal to 1. And hyperbolas are always come in pairs while parabolas are not.
How are parabolas used on tennis?

Which conic section has a directrix?
Parabolas have directori.
What happens to comets whose orbits are parabolas?
When a comet has an orbit that is a parabola it never returns. This is because parabolas never meet in the same place that they start.
How are parabolas used in real life?
Parabolas are used in real life in light reflectors on cars to create a concentrated beam of intense light. Braking distance and stopping distance are quadratic formulas so their graphs are parabolas. A ball in motion in space has a path of a parabola.

How are circles ellipses hyperbolas and parabolas used in real life?
--actually they are used in real life. parabolas are seen in "parabolic microphones" or satellites. and there are others for both ellipses and hyperbolas.
Can two parabolas of the form with different vertices have the same axis of symmetry?
The form is not specified in the question so it is hard to tell. But two parabolas with different vertices can certainly have the same axis of symmetry.
