How do you read the graph of a function?

Question

I can interpret functions in the formula form but I simply can’t understand how it can become a graph. How would you transform one into the other?

Answer 1

The function is just an instruction for putting dots on a rectangle of “graph paper”. For any position in the left/right direction, it tells you where the dot goes in the up/down direction. (Try it–plug in whatever value of x you want and it will tell you the value of y.)

If you have infinite dots, you get a line (straight or curved)–and that’s the graph of the function.
