Well plotting it on a graph may be one thing you need to do, but y may also be a value you simply need to find. It could represent just about anything. It could be a speed, pressure, force, time, profit, etc. Anything that might be represented by a function.

Euler invented this. It's good to learn, too, as this notation is *very* common through much of math, physics, and engineering. Just think of the f( ) notation as a whole, not as multiplication. And it makes good sense, too. Saying f(3) instead of f(x) makes it clear that we are plugging in the value 3 for x. In most cases it's okay to simply use y if you prefer, but understand the f(x) notation also.

all my years of high school i couldn't figure this out...

So what was the purpose of finding y. Do you plot it on the graph or what? Thanks if you reply.

Why can't you be my math teacher?

Wow, somehow I completely missed this explanation in high school. This makes functions make so much more sense! You’re a great teacher.

I wish that you tube restrict the like choice to one dislike, because people tend to forget likes in any video's.  dislike won't be mostly forgotten

how does f(x) mean y? who invented this?

[beresh]

You're making me love maths. You explain so clearly and make it look so easy. Thanks so much.

you teach this better than my math teacher. thank you.
