Answer:

(-2, 4)

Explanation:

The vertex of the absolute value function ...

f(x) = |x|

is located at (x, y) = (0, 0).

Translating the function h units horizontally and k units vertically makes the function ...

f(x -h) +k

and moves the vertex to (x, y) = (h, k).

Comparing the translated function to the one you're given, you see that ...

h = -2, k = +4

That means the vertex is located at ...

(h, k) = (-2, 4) . . . . matches the 3rd choice
