Question & Answer
Which equation does not represent a linear function of x?
1 Answer
Verified archiveThe equation that does not represent a linear function of x is:
D. y = 3x² – 2
Explanation: A linear function can be written in the form y = mx + b, where m is the slope and b is the y-intercept. The equation in option D includes x², which makes it a quadratic function, not a linear one.
