Answer:
b. x = -y2 + 2y + 5
Step-by-step explanation:
Eliminate answers a and d because neither has a negative sign (the negative sign is the reason the graph opens to the left).
Check out answer b. Suppose y = 1. Then x = -(1)^2 + 2(1) + 5 = 6.
This point (6, 1) satisfies equation b and corresponds to the right-most point on the graph.
