The function g(x) is a radical function with a square root, which means it is a transformation of the parent function f(x) = √x. The 3 in front of x indicates a vertical stretch by a factor of 3. Therefore, the parent function is simply f(x) = √x, and the answer is D.

g is related to the parent function. Identify the parent function f. g \text { is related to the parent function. Identify the parent function } f \text {. }g is related to the parent function. Identify the parent function f.
