Answer: V (4,-2)
Step-by-step explanation: The coordinate x from the vertex is
x = - (-8) / 2 = 4. Replacing the value of x, we write: y = 4^2 - 8.4 + 14;
y = 16 - 32 + 14; y = - 2.
Therefore, V (4,-2).

Step-by-step explanation:
Get the equation in the form y = ax2 + bx + c. Calculate - b / 2a. This is the x-coordinate of the vertex. To find the y-coordinate of the vertex, simply plug the value of - b / 2a into the equation for x and solve for y.
