The functions below represent the amounts of water released from two reservoirs over x weeks: Reservoir A

f(x) = x2 – 7x + 5

Reservoir B

g(x) = 3x2 – 6x + 2

The function h(x) = f(x) – g(x) represents the difference in the amounts of water released.

Determine which statements about h(x) and about the reservoirs are true. Check all that apply.

h(x) = –2x2 – 13x + 6
h(x) = –2x2 – x + 3
Reservoir A releases less water than Reservoir B over 1 week.
Reservoir A releases the same amount of water as Reservoir B over 1 week.
Reservoir A releases more water than Reservoir B over 1 week.
