1. Determine whether or not the following relations are functions. If the given relation is a function, identify the domain and range of the function, and determine further whether or not the function is one-to-one. If the function is one-to-one, find its inverse, and use your answer to verify Theorem 2 (Inverse Functions). Show complete solutions. If the given relation is not a function or if the function is not one-to-one, show a contradiction. 4. R= {(p,96), (r,99), (q,90), (t,100), (p,95)} 5. S= {(w, v), (u, x), (v, w), (z,y), (x,z)} 6. 5x - y = 15
