For more detail, below please find the table and the graph regraph with zoom 5 zoom square) which makes the tickmarks fair:
Looking at the graph and the table, we can see the point of intersection is (1,3)…now we have to read the answer carefully. Notice that answers 3 and 4 are backwards. And that answers 1 and 2 are the x value that makes the equation true. Match up the x value with the x value in the point (1,3) and voila — 2 more points!
