Set 3: Quadratic Equations (Advanced)

**Choice B is the best answer.** In vertex form y = a(x - h) squared + k, the vertex is at (h, k). So x = 8

Explanation

Answer: B

PROBLEM

For the parabola y = 1(x - 8) squared + 2, what is the x-coordinate of the vertex?

✓ Correct

Detailed Explanation

Choice B is the best answer. In vertex form y = a(x - h) squared + k, the vertex is at (h, k). So x = 8

Why others are wrong:

A: 6 is incorrect because it does not satisfy the equation.

C: 7 is incorrect because it does not satisfy the equation.

D: 10 is incorrect because it does not satisfy the equation.
