Find the linearization L(x, y) of the function f(x, y) at the point P0.
Then find an upper bound for the magnitude of the error E in the approximation
f(x, y)≈L(x, y)
over the rectangle R.
f(x, y)=xy−3y2+2,P0(1,1) R:|x−1|≤0.1,|y−1|≤0.2

1.3 and 1 1/3 are both closest to 1. hope this ; )

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
