What is the vertex of the quadratic function y = 2(x - 3)²   + 4 ?*

10 points

(3,4)

(-3,4)

(3,-4)

(-3,-4)

Solution

The vertex form of a quadratic function is generally written as:

y=a(xh)2+ky = a(x - h)^2 + k

where (h,k)(h, k) is the vertex of the parabola.

Given the function:

y=2(x3)2+4y = 2(x - 3)^2 + 4

  • h=3h = 3
  • k=4k = 4

Thus, the vertex is:

(3,4)(3, 4)

So, the correct answer is (3, 4).

Tip: The sign of hh in the vertex form y=a(xh)2+ky = a(x - h)^2 + k is always opposite when determining the vertex.
