The point P(0.25, 20) lies on the curve y = 5/x . Let @ be the point (x, 5/x). a.) Find the slope of the secant line PQ for the following values of c. If = = 0.35, the slope of PQ is: If x = 0.26, the slope of PQ is: If x = 0.15, the slope of PQ is: If I = 0.24, the slope of PQ is: b.) Based on the above results, guess the slope of the tangent line to the curve at P(0.25, 20)
