example A: Graph:
|Solution:Go into ns equation right into Y= by resolving because that y.|
Get in the Optimistic squto be root right into Y1.Enter the negati have squto be root right into Y2, or Go into the negative of Y1.If you pick ZOOM #6 (ns typical window), ns graph will certainly show up to be an ellipse rather than a circle because of the 3/2 aspect ratio that ns viewinns display (the typical viewinns screen ins not a square).pick ZOOM#5 ZSquto be come develop a viewinns home window wright here the units ~ above both axes are ns exact same length.
instance B: Graph:
|Solution:Get in ns equation into Y= by solving for y.|
