Help would be appreciated!

Let f(x) be the cubic spline from the problem below. Thus myCubicSplineEval is the function to evaluate the cubic spline f(x) and it can be used like any other Matlab function that evaluates f(x). Find all roots of f(x) and their tolerance in function with at least 8 significant digits between 7 x 9 using a root finding method. State the name of the root finding method you used.

%set data vecx = [0.0;0.5;1.0;1.5;2.0;]; vecy = [0.1,0.2,0.3,0.4,0.5];

myCubicSplineCoeffs(vecx,vecy)

%generate data from the cubic spline xvec = linspace(0,10,1000); yvec = myCubicSplineEval(xvec);

%Plot the data points and cubic spline plot(vecx,vecy,'o', 'MarkerSize',16,'MarkerFaceColor','k'); hold on; plot(xvec,yvec,'k-','Linewidth',3); legend('measured data', 'cubic spline','location','southwest');
