A vertical line can be used to test whether or not a graph is 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
True
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.
The "vertical line test" will tell you if it is a function or not. The graph is not a function if it is possible to draw a vertical line through two points.
The Vertical Line Test for Functions: If any vertical line intercepts a graph in more than one point, the graph does not define y as a function of x. By the definition of a function, for each value of x we can have at most one value for y.
The Vertical Line Test for Functions: If any vertical line intercepts a graph in more than one point, the graph does not define y as a function of x. By the definition of a function, for each value of x we can have at most one value for y.
A vertical line. Remember that one test to see if a relation is a function is the vertical line test. A vertical line would fail that of course.
I got the same things :/ what's this mean?
Determines whether a given mathematical expression is a function or not.
pregnant
A vertical line can be used to test whether or not a graph is a function.
you're not pregnant if those are the lines you see
"y = f(x) is a function if it passes the vertical line test. It is a 1-1 function if it passes both the vertical line test and the horizontal line test. " - In order to be a one-to-one function, it first has to BE a function and pass the vertical line test. For example, a relation on a graph like a circle that does not pass the vertical line test is not function nor one-to-one.
if you have only 1 line after taking your home pregnancy test it mean that you are NOT pregnant, and if there are 2 lines on your home pregnancy test, then you are pregnant but should go to a docotor to confirm it.
Not quite. You can use a vertical line test on the graph of the inverse mapping, OR you can use a horizontal line test on the original graph. The horizontal line test is used in the same way.
No. Because a vertical line will pass through two points on the graph.
