You have answered 4 out of 5 parts correctly. The point P(16, 7) lies on the curve y = va + 3. Let Q be the point (x, Va + 3). a.) Find the slope of the secant line PQ for the following values of x. (Answers here should be correct to at least 6 places after the decimal point.) If a - 16.1, the slope of PQ is: 0.1248 If x - 16.01, the slope of PQ is: 0.12498 If x - 15.9, the slope of PQ is: 0.1252 If a = 15.99, the slope of PQ is: 0.12502 b.) Based on the above results, estimate the slope of the tangent line to the curve at P(16, 7). Answer: 0.125You have answered 0 out of 2 parts correctly. For f(x) -2, find f'(x) using the definition f'(x) = lim f(x th) f(2) h f ' ( 20 ) = Using this, find the tangent line to the graph of y = 72 at x = -1. Write the equation of the line in slope-intercept form. y = -2x - 1You have answered 1 out of 3 parts correctly. Suppose f(x) = 10 - 22. (a) Find the slope of the tangent line to the graph y = f(x) when x = -1. Slope = lim f(x th) - f(ac) lim 2 h h 0 (b) Find an equation for the tangent of to the curve y = f(x) at the point (-1, 9). Tangent line: y = (c) On a piece of paper, sketch the curve y = f(x) and the tangent line together
