To analyze the transformation of the function \( y = \sqrt{x} - 3 \) from its parent function \( y = \sqrt{x} \), we should focus on the vertical transformation that occurs due to the "-3" in the equation.
- The parent function \( y = \sqrt{x} \) has its graph passing through the origin (0,0) and will rise gradually as \( x \) increases.
- The function \( y = \sqrt{x} - 3 \) indicates a vertical shift downward by 3 units from the original \( y = \sqrt{x} \).
So when comparing it to its parent function, the transformation involves shifting the entire graph downward.
Therefore, the correct interpretation is:
"This graph represents a shift down due to the change in the y-intercept from the parent function."
