SOLVE USING MATLAB

THIS IS THE CODE THAT NEEDS MODIFICATION

you are given a Matlab file. Complete the function inside this file. After that, use Newton's method to solve the nonlinear systems of equations below with an initial guess x(!) = -0.5 and x, = 1.4. (x + 3)(x} 7) + 18 = 0 sin(xze*l 1) = 0 Terminate the loop when either of these two conditions is satisfied: i. || x(i+1) xo ||
