A Circle has this form,\[\huge x^2+y^2=r^2\] A parabola has this general form,\[\huge y=x^2\] If you ignore all of the extra junk for a moment, which one does it more closely resemble? Notice the square on the y term in the circle equation.

I'm thinking parabola... is that right? :/

4. zepdrix

I'm thinking so also :O Our equation kinda looks like (if we ignore some of the junk),\[\huge x^2=4y\]Which definitely looks more like the parabola equation than the circle. right? :D

5. zepdrix

But anyway, yes you are correct! :D

yupp that is correct! Great job :)

C. Parabola

haha thank youu :)

9. matricked

its not circle bcoz here coefficient of X^2 and y^2 are different (infact y^2 is absent)

ohhh okay!! thank you :)
