Start with any one of the given ordered pairs. Take the first coordinate in the ordered pair and substitute that value for . Then do the arithmetic. If the result is equal to the second coordinate of that ordered pair, then that point is on the graph of the function, otherwise not.

Hint: Three of the given points are on the graph, one is not.

It might also be helpful to read as "the value of the function at " and to look at ordered pairs not as but as
