Question

Use the quadratic equation y = x^2 + 3x – 10.

Where does the vertex of the parabola lie?

A.
below the x-axis

B.
above the x-axis

C.
on the x-axis

D.
on the y-axis

Answer 1

first coordinate of the vertex is always \(-\frac{b}{2a}\) in your case it is
\[-\frac{3}{2}\]
to find the second coordinate, replace \(x\) by \(-\frac{3}{2}\) and see what you get

Answer 2

i am fairly sure that the answer will be negative, so it lies below the x - axis

Answer 3
