f ( x ) = 4x - x 2+K + ( 1 , 3 + k ) on the graph off K = 5 a ) write your equation after substituting the Value of K f ( x ) = 4 x - x 2 +5 b) calculate the function values, showing your calculations, then graph three secant lines 1. one through PCI. f (1 ) ) to P, (0.5, -) in one thru p ( 1, f (1) ) to P 2 ( 1. 5, - ) li. one thru P, to Pz () find the slope of each of these three secant lines D) No Derivatives Allowed here , use the results to estimate the slope of the tangent line at ( 1, 3 + K )
