The point P(4, -2) lies on the curve y = 2/(3- x). (a) If Q is the point (x, 2/(3- x)), use your calculator to find the slope mpo of the secant line PQ (correct to six decimal places) for the following values of x. (1) 3.9 (1) 3.99 - Odu () 3.999 (v) 3.9999 (v) 4.1 (vi) 4.01 (vi) 4.001 (vii) 4.0001 (b) Using the results of part (a), guess the value of the slope m of the tangent line to the curve at P(4, -2). (c) Using the slope from part (b), find an equation of the tangent line to the curve at P(4, -2).
