Q. The statement which gives the best description of location of the vertex of the quadratic trinomial $f (x) = a x^{2} + b x + c$ , with $a > 0$ and $b^{2} - 4 a c > 0$ , is

It will lie on the $y$ -axis.

It will lie below the $x$ -axis, on the $y$ -axis.

It will lie above the $x$ -axis, on the $y$ -axis.

It will not lie on $x$ -axis.

Correct answer is (d) It will not lie on $x$ -axis.
