At the beginning of a population study, a city had 350,000 people. Each year since, the population has grown by 2.1%. Let t be the number of years since start of the study. Let y be the city's population.
Write an exponential function showing the relationship between y and t.

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²
