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

Imagine you have a machine called f. you throw number in f and f gives you some number out(when possible).
When we write f(x), we mean that what we’re throwing inside is x.
For any point in the graph, the x value of the point shows what is the number we put inside, while the y value of the point shows what is the number we get out.
