Plotting the range of a variable with defined intervals.

Given f(x), I'm asked to plot f(x) with a green curve and blue x-marks on the same plot. x ranges from 0 to 1 and the intervals of the blue x-marks are 0.1. I also need to label the axes. I believe I need to use feval but I'm unsure how. Thank you!

The plot documentation shows you can specify the type of line and markers like this

x=0:0.1:1; % use colon notation to create a vector from 0 to 1 every 0.1
y=x.^2; % here for example f(x) is a parabola
plot(x,y,'-xg') % specify the a line with 'x' marker and green color '-xg'
xlabel('x'); % label axis with 'xlabel'
ylabel('y');
