The total number of seats is an auditorium is modeled by f(x) = 2x2 - 6x, where x represents the number of row of seats. How many rows are there in the auditorium
if it has a total of 140 seats?

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
