Question

Find out if a function is linear or nonlinear from a graph.

Answer 1

Linear functions make graphs that are perfectly straight lines. Nonlinear functions have graphs that are curved.

Answer 2

Explanation:

Believe it or not, we can determine whether a function is linear or nonlinear simply by looking at its graph! Because the rate at which y is changing with respect to x is constant in a linear function, the graph of a linear function is a line, as the name implies. For example, observe the graph of Sophie's function.
