I can’t see the graph you meant to include. To pick A–D I need two facts from the graph:
1. Are the endpoints at 0 and 50 pounds included (solid/filled dots) or excluded (open dots)? That determines whether the domain is (0,50) or [0,50] (or something else).
2. What is the highest cost value shown on the graph, and is that top point actually attained (solid dot) or only approached (open dot)?
If you can tell me those two things (e.g., “solid dots at 0 and 50, highest price shown is $110 at a solid dot”), I’ll tell you which answer is correct. If you prefer, re-upload the image.
