Horizonatal line test is a test use to determine if a function is one-to-one. If a horizontal line intersects a function's graph more than once, then the function is not one-to-one.
A one-to-one function is a function where every element of the range correspons to exactly one element of the domain.
Vertical line test is a test used to determine if a function is a function or relation. If you can put a vertical line through graph and it only hits the graph once, then it is a function. If it hits more than once, then it is a relation.

What does a vertical line tell you?
A vertical line can be used to test whether or not a graph is a function.
Which way is the horizantal way and which way is the vertical way?
Horizontal is the way of the horizon, and vertical is upwards. xx
What is a horizantal number line?
one
Where is y and x axis?
The y- axis in the vertical axis and the x-axis in the horizantal axis
How do you use the vetical line test to determine a function?
f(x) = x2 This is a function by the vertical line test because a vertical line drawn through this function will only intersect the function at one point
