The Deep Dive
To find the function that represents the graph of \( y = \sqrt{x} \) shifted down 4 units, we need to subtract 4 from the original equation. So, the correct function is \( y = \sqrt{x} - 4 \). However, this option isn’t presented in your list. Both options given don't correctly reflect the downward shift. It's important to remember that vertical shifts affect the constant term in the function. So when working with transformations, keep in mind that adding or subtracting affects the graph along the y-axis. Always check the effect of transformations carefully!
