Question

Determine if the following equation is a function: x=2
function
not a function

Answer 1

Not a function. Does not pass the vertical line test, because x=2 is a vertical line.

Answer 2

Not a function. The graph is a vertical line crossing x-axis at 2. It fails vertical line test for functions. You plot (2,0), (2,4), (2,-7), etc., and a function never pair any x value with more than 1 y value.

Answer 3

The given equation represents a st. ,line parallel to the y-axis and passing through the point (2,0) Since this represents 'one-many relation',the given equation is not a function.

Answer 4

it is not a funtion because x=2 graphed is a vertical line and for something to be a function it must pass a vertical line test.

The vertical line test is: You should be able to draw a vertical line anywhere on the graph and it should only go through the line ONCE. Since x=2 is a vertical line, another one drawn would pass through the origional infinaty times.

Answer 5

do 2 y points share the same x point? no

think of a circle. circles are not functions because have that property
x = 2 is a straight vertical line that starts at ( 2, negative infinity) to (2, positive infinity)

Answer 6

k ummm.... i think it's a function do the pencil test and if it runs over 2 pts at a time than it is not a function. But i think that is

Answer 7

not a function x=2 is a straight up and down line because the x coordinate is the same the whole way hope i helped hv a great day!!

Answer 8

Technically, on a graph, it would be a function where you'd get a vertical line at 2.

Answer 9

haha everyone answered differently...lol

its not a function! cuz when u do the vertical line test it hits the x-axis in more than one place for the line x=2 is a vertical line it self

Answer 10

that's the whole question?
i would say yes because x is functioning as 2 not sure though
