(4). On a piece of paper, find and sketch the domain of the function. What shape is the domain? ? Consider the function f(x, y) = arctan Find the function's range. The range is (-pi/2,pi/2) (Enter your answer using interval notation.) On a piece of paper, find and sketch a set of level curves at equally-spaced heights on the same set of axes. Try to visualize and draw the graph of the function. What shape are the level curves? ? On a piece of paper, find and sketch the boundary of the function's domain. What shape is the boundary of the domain? ?
