Can someone help with this question. “Write an equation of the inverse of the relation y=2x-3”

James is playing his favorite game at the arcade. after playing the game 3 times, he has 8 tokens remaining. he initially had 20 tokens, and the game costs the same number of tokens each time. the number tt of tokens james has is a function of gg, the number of games he plays

The table shows the balance of a money market account over time. write a function that represents the balance y(in dollars) after t years.

These tables represent a quadratic function with a vertex at (0, -1). what is the average rate of change for the interval from x = 9 to x = 10?
