Answer:
We don't have enough information to answer this question because we don't know the relationship between the functions f(x) and j(x). The fact that the minimum graph of y = j(x) is (-1,-2) only tells us about the behavior of j(x), not f(x).
If we had more information about the relationship between the two functions, we might be able to use the fact that the minimum graph of y = j(x) is (-1,-2) to make some inferences about the minimum point on the graph of y = f(x) + 7. However, without additional information, we cannot provide a specific answer to this question.
