Let g (1) give the market value (in $1000s) of a house in year 1. What does the statement g(7)-g(2) 7-2 = 5 tell you about the house? O The house's market value increased by $5000 between years t = 2 and t = 7. O The house's market value decreased by $5000 between years t = 2 and t = 7. The average house's market value between years t = 2 and t = 7 was $5000. O The house's market value increased at an average rate of $5000 per year between years f = 2 and t = 7.
