Comparing Exponential, Linear, and Quadratic Growth Answers

f(x) = x2 – 3x + 5g(x) = 2x2 – 4x – 11What is h(x) = f(x) + g(x)?

Aleka and Helene both opened savings accounts that earn 2.5% interest a year. Aleka puts $2,500 into her account. Helene put $1,500 into her account and also saves $200 cash a year.x = number of yearsAleka: f(x) = 2500(1.025)x Helene: g(x) = 1500(1.025)x + 200xWhich function represents the difference, h(x) = f(x) – g(x), between the value of Aleka’s and Helene’s total savings after x years?

f(x) = 8x2 – 2x + 3g(x) = 12x2 + 4x – 3What is h(x) = f(x) – g(x)?

Study these equations:f(x) = 2x – 8g(x) = –5xWhat is h(x) = f(x)g(x)?

A wedding planner is organizing the seating for a wedding. He can represent the number of rows by the function f(x) = 13x and the number of seats in each row by the function g(x) = 5x – 2.Which function represents the total number of seats?
