What is the domain of the function below? {(0,2), (3,1), (5,2), (8,4)}? (1point)



Is the following relation a function? {(0.3, 0.6), (0.4, 0.8), (0.3,0.7), (0.5,0.5)} (1point)

    the domain is the set of x-coordinates: {0,3,5,8}

    If any x maps to more than one y, it's not a function. So, what do you think?
