Answer 1

Explanation:

The linear function is

On a coordinate plane, a parabola opens down.

On a coordinate plane, a line curves down, levels off, and then curves down.

What is linear function?

A linear function is a function that represents a straight line on the coordinate plane.

As, linear function is a function whose graph is a straight line. Therefore, a nonlinear function has a graph which is not a straight line.
