I ran above code in MATLAB 2019a
The output was ( I've attached the output in pdf format too)
-----------------------------------------------------------

z = tf('z',1)
z'
tf(ss(z)')

q=z +1
q'
tf(ss(q)')

q=z^3-2*z^2+3*z+7
q'
tf(ss(q)')

-----------------------------------------------------------

z =

z

Sample time: 1 seconds
Discrete-time transfer function.

ans =

1
-
z

Sample time: 1 seconds
Discrete-time transfer function.

ans =

z
---
z^2

Sample time: 1 seconds
Discrete-time transfer function.

q =

z + 1

Sample time: 1 seconds
Discrete-time transfer function.

ans =

z + 1
-----
z

Sample time: 1 seconds
Discrete-time transfer function.

ans =

z^2 + z + 2.892e-17
-------------------
z^2

Sample time: 1 seconds
Discrete-time transfer function.

q =

z^3 - 2 z^2 + 3 z + 7

Sample time: 1 seconds
Discrete-time transfer function.

ans =

7 z^3 + 3 z^2 - 2 z + 1
-----------------------
z^3

Sample time: 1 seconds
Discrete-time transfer function.

ans =

7 z^4 + 3 z^3 - 2 z^2 + z + 2.425e-17
-------------------------------------
z^4

Sample time: 1 seconds
Discrete-time transfer function.
