A citrus orchard has 180 orange trees. A fungus attacks the trees. Each month after the attack, the number of living trees is decreased by one-third. If x represents the time, in months, and y represents the number of living trees, which graph best represents this situation over 5 months? Does this problem show exponential GROWTH or exponential DECAY of the number of orange trees?

• Exponential GROWTH of the number of orange trees

• Exponential DECAY of the number of orange trees
