Given the functions f(x) = x^2 + 6x - 1, g(x) = -x^2 + 2, and h(x) = 2x^2 - 4x + 3, rank them from least to greatest based on their axis of symmetry. (2 points)

1) f(x), g(x), h(x)
2) h(x), g(x), f(x)
3) g(x), h(x), f(x)
4) h(x), f(x), g(x)

How do I do that? It's a pretest but it's still for a grade :(
