if your equation looks like 2x² + 2y² = 4 , then it is a circle because a = c.
if c or a = 0, the equation is a parabola.
if a is not equal to to c, but they have the same signs, then the graph would look like a ellipse.

Quadratic Functions
stardard form is ax² + bx + cy² + dy + e= 0.
if your equation looks like 2x² + 2y² = 4 , then it is a circle because a = c.
if c or a = 0, the equation is a parabola.
if a and c have different signs, the equation is a hyperbola
if a is not equal to to c, but they have the same signs, then the graph would look like a ellipse.
