I hope the following code snippet helps
% construct transfer function using tf
g = tf(10*[1 4],[1 4 5 0]);
k= tf([1 1],[1 3]);
% obtain the overall transfer function
y_by_x = feedback(g*k,1);
% define input
t = 0:0.01:10;
w=1.7;
r = sin(w*t);
%visualize result
figure ;
lsim(y_by_x,r,t) % used to simulate response to input
the gray line in input to system and the line is blue is the system output, since the input is sinusoidal, the output will also be sinusoidal in nature by definition of LTI systems, for more help on feedback, lsim, and tf refer the following documentation
I hope this helps, please accept the answer if query resolved.
Thank you
