Q:
Find the vertex of the given function.f(x) = l x-5 l + 10The vertex is at (___, ___)
Accepted Solution
A:
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 )
