In mathematics, the horizontal line test is a test used to determine whether a
function is injective (i.e., one-to-one). Contents. [hide]. 1 In calculus; 2 In set
Note: Ever look at the horizon when the sun is rising or setting? Know why it's
called the horizon? It's a horizontal line! And just like the horizon, horizontal lines
A horizontal line is one the goes left-to-right, parallel to the x-axis of the
