Question

What is the domain of the square root function graphed below?

Answer 1

D

Explanation:

because its right

Answer 2

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

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.
