The graph of a function f(x) is shown below: plot ordered pairs negative 1, negative 3 and 0, 1 and 1, 2.2 and 2, 3
What is the domain of f(x)?
A. integers from −1 < x < 2
B. integers from −3 < y ≤ 3
C. integers from −3 ≤ y < 3
D. integers from −1 ≤ x ≤ 2

Respuesta :

we have the points

[tex]A(-1,-3)\\B(0,1)\\C(1,2.2)\\D(2,3)[/tex]      

Using a graphing tool

see the attached figure  

the domain is the interval---------> [tex][-1,2][/tex]

[tex]-1 \leq x\leq 2[/tex]      

the range is the interval--------> [tex][-3,3][/tex]

[tex]-3 \leq y\leq 3[/tex]  

therefore

the answer is the option D

integers from  [tex]-1 \leq x\leq 2[/tex]

Just took the exam and it was option D :)
