answer this please

Given f(x)=3243x3+486 (a) Find the linearization of f at x=1. Be sure to enter equation in the form y=mx+b. (b) Using the linearization model, estimate f(1.1). f(1,1) (c) Compute the actual value of f(1,1). What is the |error| between the function value and the tinear approximation? Round your answer to five decimal places. error (d) Find the relative error for f(1,1) and its estimated value L(1.1). Express your answer as a percentage and round to four decimals. Relative error =f(1,1)error=
