Function not accepting all available x values

So I wrote a simple code to get a plot of a function

x = linspace(0,100,101);

y = 4*x.*(x+1) / (4*x.*(x+1) + (sin( 8*sqrt(x+1) )).^2)

plot(x,y);

and for some reason y only comes out as a single value

Is there any reason why this might be happening?

y = 4*x.*(x+1) ./ (4*x.*(x+1) + (sin( 8*sqrt(x+1) )).^2);
