The point P116, 3} lies on the curve y = 12'} -| 4. Let Q be the point (at, {E l 4}. :1.) Find the slope of the secant line PQ for the following 1uralues of 3. (Answers here should he eonect to at least 6 places after the decimal point.) If a: = 15.1, the slope of P62 is: If n: = ll, the slope of Pt} is: If n: = 15.9, the slope of PQ is: If s: = 15.99. the slope of Hg is: I1} Based on the above results. estimate the slope of the tangent line to the curve at P[1, 3}.
