Select all that apply.
A. y = 7.4x
B. y = 2x + 52
C. y = 10x?
D. y = 5x - 3
E. y - Ž
F. y = 2x3 + 1

A linear function is represented as: ., where

This means that , and are nonlinear functions.

By comparing the given options with the above representation of a linear function, the following are linear functions

This implies that, the other options are nonlinear functions.

Hence, (c), (e) and (f) are nonlinear functions
