What type of function is y equals -7?
A linear function. It is a horizontal line at -7.
The test is used to determine whether a function is one-to-one?
horizontal line
Can a one to one function not be a function?
"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.
The horizontal change of a line?
The horizontal change is the change in x. If the line in horizontal then the horizontal change will just be its length.
What is the form of an equation for a horizontal line?
For a horizontal line, it is y= a value
Why a constant function doesn't have an inverse function?
When graphing functions, an inverse function will be symmetric to the original function about the line y = x. Since a constant function is simply a straight, horizontal line, its inverse would be a straight, vertical line. However, a vertical line is not a function. Therefore, constant functions do not have inverse functions. Another way of figuring this question can be achieved using the horizontal line test. Look at your original function on a graph. If any horizontal line intersects the graph of the original function more than once, the original function does not have an inverse. The constant function is a horizontal line. Under the assumptions of the horizontal line test, a horizontal line infinitely will cross the original function. Thus, the constant function does not have an inverse function.
Can a line be a graph of a function?
Yes the graph of a function can be a vertical or a horizontal line
Can a line be the graph of a function?
Yes the graph of a function can be a vertical or a horizontal line
What kind of function is a horizontal line?
NONE
Can the graph of a function be a horizontal line?
yeah
The horizontal line test is used to determine whether a function is?
The horizontal line test is used to determine whether a function is one-to-one and if it had a inverse.
What does a slope OF 0 tell you about a line?
It is a horizontal line.
Is a horizontal line a linear relationship?
no ,horizontal line is a linear relationship
What does it mean when a line graph is a horizontal line?
It means that the function is constant.
What kind of linear equations will give you a horizontal line?
The kind of function without an X variable.Y = 4is a horizontal line.
What test is used to determine if a graph is a function?
Horizontal line test is used for the determination of a function,if the horizontal line passes through one point of the given graph then it is a function and if it passes through more than one point then it will not a function. * * * * * No! It is a vertical line test. Consider the graph of y = sin(x): a horizontal line line will cross it twice in every 360 degrees! Convince me that y = sin(x) is not a function.
What type of function is y equals -7?
A linear function. It is a horizontal line at -7.
