D

Step-by-step explanation:

because its right

Answer 2

Answer:

The domain is $[3,\infty)$.

Step-by-step explanation:

Domain is the input to a function. The input to a function is marked along the x axis as the x values are the independent values and thus are in the domain of the function.

From the graph, the function starts at $x = 3$ when the point is (3,1) and then the graph of the moves towards infinity.

So, the domain of the function starts at 3 and move towards infinity.

Hence, the domain include the $x$ values between 3 to infinity including 3.
