Given the function below f(x) = V144x3 + 72 Find the equation of the tangent line to the graph of the function at > = 1. Answer in my + b form. L() 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. |error | ~ (Approximate to at least 5 decimal places.)
