The following table provides values of the function ƒ(x, y). However, because of potential errors in measurement, the functional values may be slightly inaccurate. Using the statistical package included with a graphing calculator or spreadsheet and critical thinking skills, find the function ƒ(x, y) = a + bx + cy that best estimates the table where a, b, and c are integers.
