Set 2: 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 = 7

Explanation

Answer: B

PROBLEM

For the parabola y = 1(x - 7) squared + 4, 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 = 7

Why others are wrong:

A: 14 is incorrect because it does not satisfy the equation.

C: 8 is incorrect because it does not satisfy the equation.

D: 9 is incorrect because it does not satisfy the equation.
