I can't see mc002-1.jpg — could you upload the image or describe the graph (type of curve, vertex or turning-point y-value, any open/closed dots, horizontal asymptotes)?
How to decide once I can see it:
- If the graph has no top or bottom (goes to ±∞ in y) the range is all real numbers.
- If it has a lowest y-value L (and never equals L because of an open dot or hole) the range is y > L; if it attains L (closed dot or continuous minimum) the range is y ≥ L.
- Similarly for a highest value U gives y < U or y ≤ U.
So check the smallest (or largest) y-value on the graph and whether that value is included. Then choose the matching option (y > 15 means minimum 15 not included; y > 35 means minimum 35 not included). Upload the picture and I’ll pick the correct choice.
