A professor of mine wants the class to turn the homework that has a graph. The guy shows the class how to do once last month and refuses to repeat it. He wants the graph with a thickness of 3, a white circle at the root (where Y=0) as I recall he draw a circle then scale down, and an arrow pointing at the root (along with its name).
The first picture is my graph, the second picture is what it supposed to look like(format).

Try this (I am leaving some details for you to discover like text on graph and axes labels):
% Definition
x = 0:0.1:10;
f = @(x) (x.*cos(x)+1);
% Find roots
r1 = fzero(f,2);
r2 = fzero(f,4);
r3 = fzero(f,8);
% Plot
grid on;
hold on;
scatter([r1 r2 r3],[f(r1) f(r2) f(r3)],150,'MarkerEdgeColor',[0 0 0],'MarkerFaceColor',[1 1 1],'LineWidth',1);
hold off;
