Answer:
k=-2.5
Step-by-step explanation:
Given is a graph V shaped two straight lines symmetrical about x=1
Hence the function willbe of the form
[tex]f(x) = |x-1|+k[/tex]
To find k
When x=1, we find the graph has a minimum at (1,-2.5)
Substitute x=1 to find f(1)
f(1) = |1-1|+k=0+k=k
Since f(1) = -2.5 from the graph we have
k =-2.5
Option a is right
