# Algebraic Geometry/Functions

Examples of functions would include ${\displaystyle 2x+3y=9}$, ${\displaystyle 4x+7z=8}$
function is denoted by symbol ${\displaystyle f(x)}$ or ${\displaystyle g(x)}$ where ${\displaystyle x}$ is the independent variable and function are written as ${\displaystyle f(x)=7x+9}$
