The value of K is option B. -3.
How did we get the value?
The graph shows that
is translated horizontally and vertically to get the function

As the function g(x) goes down three units on the y-axis then the value of k is -3. So the correct option is option B. -3.
To solve for the value of h, we use the condition (4, 0).
we have;

It could then be concluded that h is 5.
Complete question:
The graph shows that f(x)=(one-third) Superscript x is translated horizontally and vertically to get the function (one-third) Superscript (x minus h) plus k. What is the value of K?
a. -5
b. -3
c. 3
d. 5
