Matlab

1) Calculate one root of f(x)=2.75x3+18x221x12 a) Use a graphical technique in MATLAB. b) Please do your calculations by hand to determine a root x using the bisection method. Use an initial interval from -1 to 0 . Perform the computation until the absolute relative error percentage is less than 1%. c) Please do your calculations by hand to determine a root x using the false position method. Use an initial interval from -1 to 0 . Perform the computation until the absolute relative error percentage is less than 1%
