The function f (x) = x^2 is reflected across the x-axis and a stretch factor of 4 is applied to create a second function, g (x). Which of the following statements about the vertices of f (x) and g (x) is true?

a) The vertex of g (x) is 4 units to the left of the vertex of f (x).

b) The vertex of g (x) is 4 units above the vertex of f (x).

c) The vertex of g (x) is the same as the vertex of f (x).

d) The vertex of g (x) is 4 units to the right of the vertex of f (x).

e) The vertex of g (x) is 4 units below the vertex of f (x).

C. The vertexes are the same. The functions' vertex (h, k) values were not altered, just a (stretch/compress).
