Find the vertex of the given function.

f (x) = l x-5 l + 10

The vertex is at (___, ___)

When it comes to this "vertex form" type of expressions, the cheap way to get the vertex is, set the grouped terms to 0, namely

x - 5 = 0

x = 5

well, if we set x = 5, x - 5, turns to 0, and that happens when x = 5, therefore, the vertex is

| x - 5 | + 10

| (5) - 5 | ( + 10) is at (5, 10)

The vertex is (5, 10).
