Homework Statement
when asked to identify an equation as a parabola, hyperbolas, ellipses, circles, straight lines, or none of the above, how can i deduce which is which?
the problems given are:
2x^2+2y^2=9 (im pretty sure this one's a circle, just by graphing it, but id like confirmation)
x^2=16-4y^2
x^2/16 + y/25 =1
3x^2 =7 + 3y^2
x/16 + y/25 = 1
x^2 = 16 - (y-3)^2
