Answer: Option A F(x)=[tex]x^{2}[/tex]
Explanation:
Quadratic function is the function which has degree two
Degree is the highest power of a polynomial
In option B we have |x| in which degree is one hence, discarded
In option C we have [tex]x^{3}[/tex] in which degree is three hence, discarded
In option D we have x which is a linear function being of degree one. Hence, discarded.
