Answer 1

To identify the ordered pair of the endpoint for the square root function \( y = 5\sqrt{x-4} - 1 \), we can rewrite it in the form:

\[ y = a\sqrt{x-h} + k \]

where \( (h, k) \) is the vertex (or the endpoint for a square root function).

From the given function:

- The term inside the square root, \( x - 4 \), indicates that \( h = 4 \).
- The \( -1 \) outside the square root indicates that \( k = -1 \).

Thus, the vertex or endpoint is at the point \( (h, k) = (4, -1) \).

Therefore, the correct ordered pair that indicates the endpoint in standard form is:

**(4, -1)**.
