Graph 4x^2 + 4y^2 = 64. What are the domain and range? I graphed it and got a circle. I also believe that: Domain: –4 ≤ x ≤ 4 Range: –4 ≤ y ≤ 4 Please check?

OpenStudy (anonymous):

yup its a circle...

OpenStudy (anonymous):

Domain is the numbers that the x value can be right? And range is the numbers that y can be?

OpenStudy (anonymous):

You are absolutely correct. The domain and range of the circle are equal to the radius :P
