Which of the following correctly describes the nature of each curve below as either f or f ′?
*I attached the graph as a picture in the comments*
Graph A is decreasing from left to right, crossing the x axis at about 0.28, then crossing the y axis around negative 0.5. Graph B increases from the left to cross the y axis at the origin, then turns to decreasing around 0.2 comma 0.3, and crosses the x axis near 0.21.

The answer cannot be determined.
f: Curve B, f ′: Curve A
f: Curve A, f ′: Curve B
f: both Curve A and Curve B
