Which of the following functions is nonlinear?
A)4X + 2Y + 7Z
B)-4X + 2Y
C)4X + (1/2)Y + 7Z
D)4X/Y + 7Z

Question

Quizplus · Accepted Answer

The function 4X/Y + 7Z is nonlinear because it contains a term with a variable in the denominator, namely X/Y. Nonlinear functions do not exhibit a constant rate of change and cannot be graphed as straight lines. The other options are all linear functions because they do not contain any terms with variables in the denominator, and therefore exhibit a constant rate of change and can be graphed as straight lines.
