A function will always be a vertical line?
A function can never be a vertical line, because it then fails the definition of a function: every x value outputs only 1 y value. The vertical line test will determine if a relation is a function. If a vertical line intersects the graph of the function at more than one place, it is not a function.
How is y 3x a function?
y=3x is a function because if you graph it, it passes the Vertical Line Test (draw a vertical line anywhere, a function will not touch the line twice or more). Also, it only has one y value for every x value.
Why is y equals 3x a function?
y=3x is a function because if you graph it, it passes the Vertical Line Test (draw a vertical line anywhere, a function will not touch the line twice or more). Also, it only has one y value for every x value.
What is y equals x divided by 3?
An equation of a line (Linear function, first-degree function). It's a line with a slope of 1/3, meaning for every 3 increase in x, increases by 1.
Why cant a vertical line pass through a function more than once?
Because a function is defined as having distinct outputs for every input therefore... you can never have two values for one x value and you can see this relationship by drawing a vertical line.
Is there an instance when a linear equation is not a function?
Yes, a vertical line is linear, but it is not a function, because every point on the line has the same x value.
A function will always be a vertical line?
A function can never be a vertical line, because it then fails the definition of a function: every x value outputs only 1 y value. The vertical line test will determine if a relation is a function. If a vertical line intersects the graph of the function at more than one place, it is not a function.
Is the graph of every line a function?
No. One argument of function may have only one value. So, if it has more than one value, it is not a function.
How is y 3x a function?
y=3x is a function because if you graph it, it passes the Vertical Line Test (draw a vertical line anywhere, a function will not touch the line twice or more). Also, it only has one y value for every x value.

y=3x is a function because if you graph it, it passes the Vertical Line Test (draw a vertical line anywhere, a function will not touch the line twice or more). Also, it only has one y value for every x value.
What is the horizantal line test and vertical line test?
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.
Is a horizontal line a function?
Yes, because for every X input there are multiple y values.
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 is a function that forms a line when graphed called?
It is a continuous function. If the line is a straight line, it is a linear function.
How can you tell if a graph is a function?
A graph is a function if every input (x-value) corresponds to only one output (y-value). One way to check for this is to perform the vertical line test: if a vertical line intersects the graph at more than one point, the graph is not a function.
What is y equals x divided by 3?
An equation of a line (Linear function, first-degree function). It's a line with a slope of 1/3, meaning for every 3 increase in x, increases by 1.
Why would you use the vertical line test?
To see if a graph is a function. There is only one x for every y!
