Question: Since only changes in potential energy are important in any problem, a student decides to let the elastic potential energy of a spring be zero

Since only changes in potential energy are important in any problem, a student decides to let the elastic potential energy of a spring be zero when the spring is stretched a distance x₁. The student decides, therefore, to let U = 1/2 k(x - x₁)². Is this correct? Explain.
