Question 238483What is the domain and range to this function: 16y^2/9 + 4x^2/25 = 1 --- Rewrite as: y^2/(9/16) + x^2/(25/4) = 1 --------------- This is an ellipse with seim-major axis = (5/4) and semi-minor axis = (3/4) --- The center is at (0,0) ------------------------------ Domain: -5/4 <= x <= 5/4 Range: -3/4 <= y <= 3/4 ============================== Cheers, Stan H.
