The graph shows the axis of symmetry for a quadratic function f (x). Which could be the function? f (x) = (x + 4) 2 f (x) = x2 + 4 f (x) = (x - 4) 2 f (x) = x2 - 4

    The answer is C. Just plug it into the graph

    f (x) = (x-4) ^2

    Either x^2 + 4 or x^2 - 4 would work since the other two functions apply horizontal shifts and move the function off of the y-axis.
