Learn about f (x), a South Korean girl group that debuted in 2009 and disbanded in 2019. Find out their names, positions, facts, ideal types, and more.
Learn the definition, examples and types of functions, and how to write them using f(x) notation. A function relates an input to an output, and has special rules of covering every element and being single valued.
The f is just a way for you to know that when you see f(x) to treat it as a function and not mistakenly treat it as multiplying one variable by the other (it DOES NOT mean f multiplied by x). It does not have to be an f, it can be any symbol and using different symbols such as h(a) helps differentiate one function from another.

Jan 21, 2014 · The graph of $f(-x)$ is the mirror image of the graph of $f(x)$ with respect to the vertical axis. The graph of $-f(x)$ is the mirror image of the graph of $f(x)$ with respect to the horizontal axis. A function is called even if $f(x)=f(-x)$ for all $x$ (For example, $\cos(x)$).
