What is the vertex of y=x² – 8x + 14
2 answers:
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).
Answer:
-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.
