Homework Help: Math

Posted by Holly on Wednesday, August 15, 2012 at 8:32pm.

When talking about a function f(x) is the f always the y point on a graph? I don't understand my book because it says f can be any letter. If f can be any letter and the question is f(6.9) and 6.9 is on the x and y axis then how do you know what to do?
