If a mass m is placed at the end of a​ spring, and if the mass is pulled downward and​ released, the​ mass-spring system will begin to oscillate. the displacement y of the mass from its resting position is given by a function of the form ​y(t)​, where is a constant that depends on the spring and the mass. show that the set of all functions of this form​ (with fixed and and ​arbitrary) is a vector space.
