Using translation concepts, it is found that the value of k is of k = -2.5.
What is a translation?
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The parent absolute value function is defined by:
g(x) = |x|
In this problem, the function was shifted one unit to the right and 2.5 units down, hence it is given by:
f(x) = |x - 1| - 2.5.
Comparing with the equation given, that is:
f(x) = |x - h| + k.
We have that h = 1, k = -2.5.
