Suppose that f(z, y) is a smooth function and that its partial derivatives have the values, f-(-8, -4) = 2 and fy(-8, –4) = -3. Given that f(-8,-4) = –9, use this information to estimate the value of f(-7, –3). Note this is analogous to finding the tangent line approximation to a function of one variable. In fancy terms, it is the first Taylor approximation. Estimate of (integer value) f(-8,-3) Estimate of (integer value) f(-7,-4) Estimațe of (integer value) f(-7,-3)
