List the x values of each point to construct the domain
Domain = {12,23, 37, 46}

List the y values of each point to construct the range
Range = {0,-9,8}

Since we have a repeated x, x = 12, this means that we don't have a function. To have it be a function, each x needs to pair up with exactly one y value.
