A function is a relation in which each element of the domain is paired with EXACTLY one element of the range. 16The notation $f (x) = y$, which reads $f$ of $x$ is equal to $y$. Given a function, $y$ and $f (x)$ can be used interchangeably. DATE. Some filters moved to Formats filters, which is at the top of the page. For instance, f(x) = root over x is an undefined function when the value of x is negative. As we can see, any vertical line will intersect the graph of $y=|x|2$ only once; therefore, it is a function. Simplify $\frac { g ( x + h ) - g ( x ) } { h }$ given $g ( x ) = m x + b$. The $x$- and $y$-axes break the plane into four regions called quadrants7, named using roman numerals I, II, III, and IV, as pictured. 10 0 obj Functions are compactly defined by an algebraic equation, such as f(x) = | x | 2. 3. Form a relation from A to B to show whether the students belong to any of the four sections. We can see that $g(x)=2$ where $x=5$; in other words, $g(5)=2$.
