2(c)  take any (x,y) - suppose (0,3) (-1,-4) (-2,4) (3,-2)

then f(x,y) = (0-3,0+3) = (-3,3)
               = (-1+4, -1-4) = (-3,-5)
               = (-2-4, -2+4) = (-6,2)
               = (3+2, 3-2) = (5,1)

so the range could be in any quadrant - matlab pura plane gets covered anyway.
(others please correct me if the reasoning is wrong!)

ya the process is correct .. one must take examples in order to solve these

[mrittik]

absolutely correct process....linearly transformed function is given...other way to solve to make easy its linear transformation...but tsuki's process is easy & understandable.....gracias
