Determine whether f (x) = 5 + and g(x) = 9x + 12 are inverses. Explain your reasoning. O A) Yes; [f • g)(x) = x and [g ºf)(x) = x.
O B) Yes: [f •g] (6) = x + and [g of)(x) = x + 24.
O C) No; (fºg)(x) = x and [g of)(x) = x.
OD) No; [f • g] (x) = x + and [8 •f](x) = x + 24.

Acaterer charges $500 plus $30 per guest to cater a wedding. walt and traci don't want to spend more than $8000 on catering. write and solve an inequality in terms of the number of guests, g, that can be invited. a) 30g ? 8000; g ? 267 b) 500g < 8000; g < 16 c) 500 + 30g < 8000; g < 250 d) 500 + 30g ? 8000; g ? 250
