The function is nonlinear.
Here's why:
1. Nonlinear Form: The function represents a square root relationship between y and x. It is not in the form of y=mx + b, which is the standard form of a linear function. Linear functions must have y as a linear function of x, meaning y should not involve square roots or other nonlinear operations of x.
