How can functions relate to real life?

Answer 1

Just as "life goes on," so does the linear function. Reading a linear function on a graph from left to right, sometimes the line goes up (positive slope) and sometimes it goes down (negative slope). The same is true with life. You will always have your ups and downs, but life goes on. The main thing is keep your head up, and try keep the positives going as long as you can. If you find yourself going negative, figure out how to turn things around and go positive again.
