    Answer:

    A) y = x²- x

    Step-by-step explanation:

    A linear function will have y equal to x, without x being manipulated by a square root, exponent, etc.

    y = x²- x has x being squared.

    This will create a graph of a parabola, which is not linear.

    So, since it is a quadratic instead of a line, answer choice A) y = x²- x is correct.
