Practice for Horizontal Line Test.
1 : Consider the following graph.
Does this graph represent a function?
Remember that the Vertical line test tells you if a graph is likely to represent a
function.
1.1 : Is this graph invertible?
Recall that the Horizontal line test tells you if the graph is likely to be invertible.
2 : Consider the following graph.
Does this graph represent a function?
Remember that the Vertical line test tells you if a graph is likely to represent a
function.
2.1 : Is this graph invertible?
Recall that the Horizontal line test tells you if the graph is likely to be invertible.
3 : Consider the following graph.
Does this graph represent a function?
Remember that the Vertical line test tells you if a graph is likely to represent a
function.
3.1 : Is this graph invertible?
Although this may appear to have a horizontal segment near the origin, it in fact
does not. This is a good example of why graphing can be misleading at times.
4 : Consider the following graph.
Does this graph represent a function?
Remember that the Vertical line test tells you if a graph is likely to represent a
function.
4.1 : Is this graph invertible?
Recall that the Horizontal line test tells you if the graph is likely to be invertible.
5 : Consider the following graph.
Does this graph represent a function?
Remember that the Vertical line test tells you if a graph is likely to represent a
function.
5.1 : Is this graph invertible?
Recall that the Horizontal line test tells you if the graph is likely to be invertible.
6 : Consider the following graph.
Does this graph represent a function?
Although this may look like it has a vertical segment right near the origin, it in fact
doesn’t. This is a good example of why graphing can be a bit misleading at times.
6.1 : Is this graph invertible?
Recall that the Horizontal line test
tells you if the graph is likely to be invertible.
