Question

To find the vertex, What must you do with the value you get from the formula −b/2a

the options are
A. That value is your vertex
B. I have no idea, I haven't listened all week
C. Plug it into original equation
D. Plug it into quadratic formula

Answer 1

To find the vertex, you need to plug the x-coordinate obtained from the formula -b/2a into the original equation.

Step-by-step explanation:

The value obtained from the formula -b/2a is the x-coordinate of the vertex of a quadratic equation. This value represents the axis of symmetry of the parabola. To find the vertex, you need to substitute this x-coordinate back into the original equation to find the corresponding y-coordinate. Therefore, the correct option is C: Plug it into the original equation.

Answer 2

C.

Step-by-step explanation:

You would need to plug it into your example equation. This is because you would need the slope of that equation. Hope this helped you out!!!
