% conditional
x= -5:0.005:15;
for k=1:length(x)
if x(k)<0
y(k)=sqrt(x(k)^2+1);
elseif x(k)<=10
y(k)=3*x(k)+1;
elseif x(k)>=10
y(k)=9*sin(5*x(k)-50)+31;
end
end
plot(x(k),y(k),'*--r','linewidth',2,'markeredgecolor','k'),xlabel('x'),ylabel('y')

plot(x,y,'*--r','linewidth',2,'markeredgecolor','k')
You were asking to plot only the very last point, x(k) and y(k)
