Ran in:
I have function
q = [0:0.01:2];
plot(20*q.^2, q.^2)
It's just a straight line. I want to move it from x = 0 to x = -50. I tried circshift but that didn't work. Any ideas?
q = [0:0.01:2];
plot(circshift(20*q.^2, -50), q.^2)

Ran in:
circshift is going to shift the position of your data, but not its value.
Why not simply -50.
q = [0:0.01:2];
plot(20*q.^2-50, q.^2)

If I am not wrong you want to achieve something like this only right ?
You can achieve this easily by following changes in code :
q = [0:0.01:2];
plot(20*q.^2-50, q.^2)
