What is the vertex of the absolute value function defined by ƒ (x) = |x - 7| + 1?

(7,1)

(-7,-1)

(-7,1)

(7,-1)

The general formula for an absolute value function is f (x) = a|x - h| + k. in this formula, your vertex is (h, k).

all you have to do to answer this question is view (h, k) in your formula f (x) = |x - 7| + 1

7 is in the place of h and 1 is in the place of k. this makes your vertex (7, 1).
