The graph shows the axis of symmetry for a quadratic function f(x).

On a coordinate plane, a vertical dashed line at (4, 0) is parallel to the y-axis.

Which could be the function?

f(x) = (x + 4)2

f(x) = x2 + 4

f(x) = (x – 4)2

f(x) = x2 – 4

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

Step-by-step explanation:

When plotted upon a graph, the function passes through the line. You can find the vertex by using the formula: f(x) = a(x - h)^2 + k

h = 4, meaning the vertex is (4, 0)

Hope this helps!
