Question

On a coordinate plane, an absolute value graph has a vertex at (1, negative 2.5).
The graph shows the function f(x) = |x – h| + k. What is the value of k?

k = –2.5
k = –1
k = 1
k = 2.5

Answer 1

k = -2.5

Explanation: For f(x) = |x - h| + k the vertex is at (h, k). Since the vertex is (1, -2.5), k = -2.5.
