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).
