You can put this solution on YOUR website! 3y2-x2=25

Do you have a question?
If you want to graph that, get the (free) software at

Use "Function", the Insert Relation, unless you solve for y.
----------------------
If you solve for y,
y = sqrt(25-x^2)/3
use Function, then Insert Function,
then the software can find tangents, areas, derivatives, etc.
