Question

The graph of a function f(x) is shown below:

plot ordered pairs negative 1, negative 3 and 1, 0 and 1, 2.2 and 2, 3

What is the domain of f(x)?

integers from -1 < x < 2

integers from -3 < y ≤ 3

integers from -3 ≤ y < 3

integers from -1 ≤ x ≤ 2

Answer 1

I don't know ur answer but I can tell you that the domain is all of the x variables and the dependent variable is all of the y variables

Answer 2

I can get some people to answer it for u though

Answer 3

Thank you.

Answer 4

ur welcome

Answer 5

(-1,-3) , (1,0) , (1,2.2) , (2,3)

domain is x values ... -1,1,2
so...
-1 <= y <=2 .... I think

Answer 6

ANS: Domain,x\[x \in \left[ -1,2\right]\] . But to be specific this graph is not a function because for x = 1 we are getting two output y = 0,2.2 . We can call it Relation .

Answer 7

oh...your right...this is not a function because it has 2 x values that are the same

Answer 8

i am so confused @PrashantSingh

Answer 9

integers from -1 < x < 2 ?

Answer 10

In simple term Domain of any function f(x) means all the values of x which are on GRAPH of f(x).
For ex, if we put x=2 in f(2) we get 3 so we do have a corresponding value for the x = 2 is y=3 . So x = 2 is in domain of f(x) .
