The tuition at a public university was $21,000 in 2008. Between 2008 and 2010, the tuition had increased by 15%. Since then, it has continued to grow exponentially. Select all statements that describe the growth in tuition cost. A: The tuition cost can be defined by the function f (y) = 21, 000 · (1.15)i, where represents years since 2008. B: The tuition cost increased 7.5% each year. C: The tuition cost increased about 7.2% each year. D: The tuition cost roughly doubles in 10 years. E: The tuition cost can be approximated by the function f (d) = 21,000 · 2ª , where d represents decades since 2008
