Can you help with this math problem using K=2? PROBLEM: Given f(x)=4x - x2 + k & (1,3) on the graph of f. Instructions a) Graph secant lines thru P(1,3+k) to each point (2,__ ); (1.5,__); (0.5,__) b) Find the slope of each secant line c) NO DERIVATIVES ALLOWED HERE! Use the results to estimate the slope of the tangent line at (1,3+k). d) How would you improve your approximation
