Standard form of a sideways parabola:
Given equation:
Add x to both sides:
--------------------------------------------------------------------------------------------
<u>Standard form of circle equation</u>
(where (a,b) is the center and r is the radius)
Given equation:
Group like terms:
Divide by 2:
Factor by completing the square for each variable:
Rearrange into standard form:
Therefore, the circle has a center at (4.5, 2.5) and a radius of √23
