What is the vertex of the absolute value function defined by f(x) = 1x + 21 +4?
O (2.4)
O (-2,-4)
O (-24)
O 12,-4)

  (-2, 4)

Step-by-step 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

the perimeter is increased by a factor of 2

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
