Shifting a line on the x-axis ONLY

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)

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)

q = [0:0.01:2];
figure
plot(20*q.^2, q.^2)
hold on
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)
