How to check the state response and output response of a state space model

I now have a SISO state space model like below and get the transfer function, so how can I use MATLAB code to check its state response and output response? Is there any specified codes? Thank you!

A=[0 1 0 0 0 0
   0 0 0 0 0 0
   0 0 -1 1 0 0
    0 0 0 -1 1 0
    0 0 0 0 -1 0
    0 0 0 0 0 -2];
B=[0;1;0;0;1;1];
C=[0 0 1 0 0 1];
D=0;
sys = ss(A,B,C,D);
TF=tf(sys)
