Adriena’s strategy for checking that the functions f(x) and g(x) are inverses is to think of them as stacked function machines. she starts by choosing an input to drop into f(x). then she drops the output from f(x) into g(x). if she gets her original number, she is pretty sure that the two equations are inverses. question: is adriena’s strategy sufficient? is there anything else she should test to be sure?

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling
