The function y=5x²−7 is nonlinear.

Here's why:

Form of the Function: A linear function is characterized by a constant rate of change (slope). It typically has the form y=mx+b, where m and b are constants. In y=5x²−7:

There is a squared term (x²), which is a characteristic of a quadratic function, not a linear function.

The function includes a constant term (−7), which affects the y-values independently of the x-values.
