Question

Which equation represents a linear function?

y = 2x²
y = x³
y = -4x + 5
y=-3x² + 2

Answer 1

Explanation:

I think it is the third one.

You cannot have an x squared or cubed because then it would have a repeating x value which would not represent a linear function.

the answer is y=-4+5

I hope this helps and is correct
