Question

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

a. (7,1)(
b. (-7,-1)(
c. (-7,1)(
d. (7,-1)

Answer 1

(7,1)

Explanation:

Answer 2

The vertex of function y = |x| is (0; 0).
We have: f(x) = |x - 7| + 1
shift the graph of the function y = |x| 7 units right and 1 unit up. Then the vertex of function f is (7; 1).
Your answer is A. (7; 1)
