To determine which equations describe a nonlinear function, we need to identify those that cannot be expressed in the form y=mx+b, where m and b are constants. Nonlinear functions typically involve terms like x², √x, 1/x, etc., or are not expressible as a simple linear relationship between x and y.

Let's analyze each equation:

A: =3−7y=3−7x

This equation is linear because it is in the form y=mx+b, where m=−7 and b=3.

Nonlinear function: No

B: y²=3x

This equation involves y², which represents...
