The correct answer is option D. Z.
Explanation:
- The graph which best represents the new function is Graph Z.
- As, if (a, b) is a point in the graph of f(x), then (a, b + d) is a point in the graph of f(x) + d.
- Linear functions are the algebraic equations whose graphs are straight lines and have unique values for their slope and y-intercepts.
- So, the graph which best describes the new function is graph Z.
