For the parabola y = 3(x - 6) squared + 5, what is the x-coordinate of the vertex?
A.✓ Correct
6
B.
12
C.
5
D.
8
Detailed Explanation
Choice A is the best answer. In vertex form y = a(x - h) squared + k, the vertex is at (h, k). So x = 6
Why others are wrong:
B: 12 is incorrect because it does not satisfy the equation.
C: 5 is incorrect because it does not satisfy the equation.
D: 8 is incorrect because it does not satisfy the equation.
