Question

the graph shows a function. is the function linear or nonlinear?

Explanation:

Step1: Recall linear function graph

A linear function's graph is a straight line (or collinear points for discrete data), with constant slope (rate of change).

Step2: Analyze given graph

The plotted points do not form a straight line. The slope between consecutive points changes (e.g., check the steepness or the line connecting them—they curve, not stay straight). So the function is nonlinear.

Answer:

nonlinear
