f(x) = 128x + 384 Find the equation of the tangent line to the graph of the function at x = 1. Answer in ma + b form. L(x) = = Use the tangent line to approximate f(1.1). L(1.1) = Compute the actual value of f(1.1). What is the error between the function value and the linear approximation? Answer as a positive value only. Jerror] = (Approximate to at least 5 decimal places.)
