figure()
x = linspace(0,1000);
y1 = (sqrt(2)*sqrt(x.^4 + 9)) ./ (2*x.^2);
plot(x,y1)
xlim([1,2])
ylim([0.8,2])

Your plot limits are outside of the range of the data.
Also you don't have enough (or any data points) in the range of x that you are plotting.
If you truly want to plot for x between 1 and 2 try
figure()
x = linspace(1,2); % just range of interest
y1 = (sqrt(2)*sqrt(x.^4 + 9)) ./ (2*x.^2);
plot(x,y1)
xlim([1,2])
ylim([0.8,2])
