pls help

For the function f(x) = - 18 (7x4+x3-6x2-x+1)6 use the formula dy - f'(x) dx and perform MARGINAL ANALYSIS to find dy , the differential value of f(a) at x = 3 when Ax = 0.06. Section 3.8 O dy = -3.71 x 10-16 O dy = 3.71 x 10-16 O dy = -3.97 x 10-16 O dy = 3.97 x 10-16 O dy = -3.84 x 10-16 O dy = 3.84 x 10-16
