Question

Which of the following represents the vertex points of the curve obtained by plotting $y=2x^2$?

• A. {0,0}
• B. {0,7}
• C. {7,0}
• D. None of these

Answer 1

The correct option is A {0,0}

The graph obtained for the polynomial $x^2-2x-3$ is a parabola. The vertex of the curve is $V=(\frac{-b}{2a},\frac{4ac-b^2}{4a})$.
Here the values of b and c =0, hence vertex point is {0,0}.
