Algebra-1

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.

2. Graph Shape: When you graph
