What is the domain of the function in the graph?
A. -2<=x<=2
B. 0<=x<=2
C.
x is all real numbers less than or equal to 4
D.
x is all real numbers
The domain of a function is the set of all possible input values (x-values) for which the function is defined.
Looking at the graph alone, we can see that there are no restrictions or gaps in the x-values. The graph stretches infinitely in both positive and negative directions. Therefore, the domain of the function in the graph is all real numbers.
The correct answer is: D. x is all real numbers.
