Some Examples of Parabola

Example: 1
y2=4ax
y^2=4ax
( NOTE: We take the value of "a"equal to 1)

Example: 2
y2=-4ax
y^2=-4ax
( NOTE: We take the value of "a"equal to 1)

Example: 3
x2=4ay
x^2=4ay
( NOTE: We take the value of "a"equal to 1)

Example: 4
x2=-4ay
x^2=-4ay
( NOTE: We take the value of "a"equal to 1)
