For a constant function like that, you could just do it geometrically:
f = 2;
xrange = [0.1 0.5];
s = f*abs(diff(xrange))
For a general symbolic approach, start with something like this instead
syms x
f = 2 + 0*x; % this just forces f to be a symbolic expression
s = int(f,[0.1 0.5])
s = double(s) % maybe you want a numeric representation instead
Try another
f = 2*sin(x) + 5*x + 3*x^2; % a bit more complicated
s = int(f,[0.1 0.5])
