Q.4 Use Newt onsRoot method to solve f(x)=0.5e2+x40=0. Use initial estimate as x=4, and execute 11 iterations. True solution of this function is x=ln(80)2. For each iteration calculate the True Relative Error(TRE) and the Estimated Relative Error (ERE). Display the results in a four column array, first column as number of iterations, then numerical solution xNS in the second column, TRE and ERE in the third and fourth columns, respectively. Plot this matrix. Include answers in the word file
