Set 1: Quadratic Equations (Advanced)

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

Explanation

Answer: C

PROBLEM

For the parabola y = 1(x - 8) squared + 3, what is the x-coordinate of the vertex?

✓ Correct

Detailed Explanation

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

B: 16 is incorrect because it does not satisfy the equation.

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