ANSWER
D. the graph of d(x) will be 25 units below the graph of f(x).
EXPLANATION
The graph of
[tex]f(x) = {x}^{2} [/tex]
is the base function.
The graph of
[tex]d(x) = {x}^{2} - 25[/tex]
is a vertical translation of the base function 25 units down.
This implies that, the graph of d(x) will be 25 units below the graph of f(x).
Therefore the correct answer is D.
