Graph x^2+9y^2=25. what are the domain and range?

The domain and range of an equation are the values of x and y that will make the equation true or make the equation possible to solve. The given equation is an equation of a circle. The values of x and y that would make this equation possible to solve ranges from negative to positive values. If we take y as zero, x values can range from negative 5 to positive 5. If we take x as zero, y values can range from -5/3 to 5/3.
