Reset the point's X-axi

if the following activity I would like to reset the point’s x-axis to zero when pressing the button. otherwise I would like the students to drag the point and visualize the ( a , f(a) ) values.

How it can be done ? thanks

Reset x-value

Jay shared a solution to a similar problem here. I’m happy to help tailor his example to your specific use case, if you want.

What a help, beautiful solution.

thanks a million.
