Question

The vertex of the curve obtained by plotting $y=-3x^2$ is ___ .

• A. {0,0}
• B. {0,1}
• C. {1,0}
• D. Cannot be determined

Answer 1

The correct option is A {0,0}

From the given polynomial, a=-3,b=0,c=0.
The curve obtained is parabola and the vertex is $(\frac{-b}{2a},\frac{4ac-b^2}{4a})$. By solving, the vertex of the parabola obtained is {0,0}.
