For a relation to be a function every x value will have a single y value.
The first one has two x values of -2 but their y values are different so can’t be a function.
The second one has two 10’s with different y values so isn’t a function.
The 3rd one has 1 and -1 with the same y value, so isn’t a function.
The correct answer is the 4th choice
Your best bet is to make a table of the x and y values.
Then plug -2, -1, 0, 1, and 2 in for x, into the equation to get the y values. That's how you get your points.
