What type of conic session if given by the equation 16x^2 + 4y^2 = 16. Identify its domain and range.
The given equation is 16x^2 + 4y^2 = 16, which can be simplified by dividing both sides by 16:
x^2/1 + y^2/4 = 1
This is the equation of an ellipse with horizontal major axis. The domain of x is (-1, 1), and the range of y is (-2, 2).
