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

When a function is described as “y = [something] x” or “f(x) = [something] x”, that’s just a way of saying “if you fill in x and do [something] with it, you get the matching y value. You can do this by hand with a few x-y pairs, draw them in a coordinate system, and connect the literal dots — that’s a graph right there.
