What is the vertex of the absolute value function below? (4, –1) (1, –4) (1, 4) (4, 1)

I will work this question for you using the graph attched which belongs to a question with the same statement of yours and whose solution is one of the points of the list of choices.

The vertex is the point where the function changes direction, in this case from growing to decrease.

That is the point wiht x-coordinate 4 and y-coordinate 1, so the point is (4,1).

(4,1)

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
