This graph is an example of A. a linear function
B. a nonlinear function
C. neither a linear nor nonlinear function - it is not a function at all?

option A is correct. this graph is a linear function

Step-by-step explanation:

Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept

C.

Step-by-step explanation:

It is not a function at all because it does not have necessary properties of a function, it is just a graph
