Answer:
D.It is true because its domain of all real numbers greater than or equal to -7 and less than 2.
Step-by-step explanation:
We have to find that graph which represent a function whose domain of all real numbers :greater than or equal to -7 and less than 2.
A.Graph A does not represent that function because its domain of all real numbers greater than -2 and less than or equal to 7.It is not true.
B.Graph B does not represent that function because its domain of all real numbers greater than or equal to -4 and less than 1.
C.It is not true of all real numbers because its domain of all real numbers greater than or equal to -3 and less than 2.
D.It is true because its domain of all real numbers greater than or equal to -7 and less than 2.
Hence, option D is true.
