At the point corresponding to (2,1) is the function increasingdecreasing withorrespect to x? At the point corresponding to (4, 2) is the function increasingrespect to y?decreasing withor (c) Suppose a bug is walking along the graph of f(x, y). If the bug walks in a straight line from the point corresponding to (1,3) to the point corresponding to (4, 1), is the bug walking uphill or downhill?
