Is the equation a linear function or nonlinear function?

Nonlinear function

Step-by-step explanation:

To know - linear vs nonlinear

[] A linear function is a straight line. Examples such as y=3x + 3 or y= -4x + 1

[] A nonlinear function is not a straight line. This is usually because it contains exponents.

[] Since the function has a square root, and there are two answers for each square root problem, this is not a linear function.
